Multiplication Table Of 123
The table of 123 is the list of products you get when you multiply 123 by each whole number in turn. Because its digits are 1, 2, 3, the number splits cleanly into $100 + 20 + 3$, so every row is three easy pieces added together.

What Is The Table Of 123 In Words?
Reading the table aloud builds the rhythm before the numbers stick.
One times 123 is 123
Two times 123 is 246
Three times 123 is 369
Four times 123 is 492
Five times 123 is 615
Six times 123 is 738
Seven times 123 is 861
Eight times 123 is 984
Nine times 123 is 1107
Ten times 123 is 1230
What Is The 123 Times Table?
The 123 times table is repeated addition of 123. Each row adds one more group of one hundred twenty-three, so the table answers "how much is 123, added to itself, again and again?"
Built from the ground up, the ladder looks like this:
$123$
$123 + 123 = 246$
$123 + 123 + 123 = 369$
$123 + 123 + 123 + 123 = 492$
Multiplication is the shortcut for this stacking, which is why $123 \times 4$ and "four one-hundred-twenty-threes added together" both give 492.
What Are The Multiples Of 123?
The multiples of 123 are the numbers you reach by skip-counting in one-hundred-twenty-threes. The first twenty are:
123, 246, 369, 492, 615, 738, 861, 984, 1107, 1230, 1353, 1476, 1599, 1722, 1845, 1968, 2091, 2214, 2337, 2460.
Every entry in the table of 123 is a multiple of 123, and because $123 = 3 \times 41$, every one is also a multiple of 3. That is why the digits of any product add up to a multiple of 3 — a quick check you can run on your own answer.
How To Learn The 123 Times Table (Patterns, Not Memorizing)
Bhanzu teaches the few patterns that generate a table rather than drilling its facts into recall. The table of 123 is built from parts you already know, so you can rebuild any row by reasoning instead of reciting it. Seeing that structure is the number sense that algebra later leans on.
Every pattern below comes from how 123 is composed: $123 = 100 + 20 + 3$, $123 = 120 + 3$, and $123 = 3 \times 41$.
Pattern 1: Split by place value. Read 123 as $100 + 20 + 3$, so $123 \times n = 100n + 20n + 3n$. For $123 \times 3$: $300 + 60 + 9 = 369$, and the three parts even line up as 3, 6, 9.
Pattern 2: Round down to 120. Because $123 = 120 + 3$ and $120 = 12 \times 10$, you can lean on the 12 times table: $123 \times n = 120n + 3n$. For $123 \times 4$: $120 \times 4 = 480$, then add $3 \times 4 = 12$, giving 492.
Pattern 3: Watch the units digit. Adding 123 raises the units digit by 3, so the last digits run 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and then repeat. If your units digit breaks that chain, you added wrong.
Pattern 4: Check with the digit sum. Since $123 = 3 \times 41$, every product is a multiple of 3. Add the digits of your answer - for 738 that is $7 + 3 + 8 = 18$ - and if the total is not a multiple of 3, the answer is off.
How Do You Read And Use The Table Of 123?
Read each row left to right: $123 \times 6 = 738$ is "one hundred twenty-three multiplied six times gives seven hundred thirty-eight." The first number is the group size, the second is the count of groups, and the product is the total.
To learn it, recite the rows and lean on the $100 + 20 + 3$ split as you go, then quiz yourself in shuffled order so you are recalling facts, not chanting them. If a row slips, rebuild it from the three place-value parts rather than guessing.
Where Does The Table Of 123 Appear?
One hundred twenty-three shows up wherever a fixed batch of 123 repeats. A ferry licensed for 123 passengers scales on this table, so four crossings carry $123 \times 4 = 492$ people. It also appears in pricing set at 123 rupees a unit, where five units cost $123 \times 5 = 615$, and in production runs of 123 parts a shift, where six shifts make $123 \times 6 = 738$ parts.
Solved Examples Of The Table Of 123
Example 1
What is $123 \times 3$?
Split by place value: $100 \times 3 = 300$, $20 \times 3 = 60$, and $3 \times 3 = 9$.
$300 + 60 + 9 = 369$
Final answer: $123 \times 3 = 369$.
Example 2 (Wrong path first)
A depot ships 123 crates per truck. How many crates on 4 trucks?
Wrong attempt. The rusher splits 123 into $100 + 23$, multiplies the hundred, then tacks on a bare 23: $400 + 23 = 423$.
Why it breaks. The 23 also has to be counted four times, not once, so 423 leaves out three of the four batches of 23.
Correct. Multiply both parts: $100 \times 4 = 400$ and $23 \times 4 = 92$, so $400 + 92 = 492$.
Final answer: 492 crates.
Example 3
Find $123 \times 12$.
Place value: $100 \times 12 = 1200$, $20 \times 12 = 240$, and $3 \times 12 = 36$.
$1200 + 240 + 36 = 1476$
Final answer: $123 \times 12 = 1476$.
Example 4
$123 \times {?} = 615$.
Divide to find the missing factor: $615 \div 123 = 5$.
Final answer: $123 \times 5 = 615$.
Example 5
A printer runs 123 sheets a minute. How many in 9 minutes?
$123 \times 9 = 120 \times 9 + 3 \times 9 = 1080 + 27 = 1107$.
Final answer: 1107 sheets.
What Are Common Mistakes With The Table Of 123?
Mistake 1: Splitting the number but not the multiplier
Where it slips in: Breaking 123 into $100 + 23$ and multiplying only the 100 by the row number.
Don't do this: Writing $123 \times 5 = 523$ (that is $100 \times 5$ with a bare 23 added).
The correct way: Multiply both parts by 5: $100 \times 5 = 500$ and $23 \times 5 = 115$, so $123 \times 5 = 615$.
Mistake 2: Misreading the neat 1-2-3 digits
Where it slips in: Assuming the tidy digits mean every product stays tidy.
Don't do this: Writing $123 \times 7 = 777$ because the digits "should" match.
The correct way: Work it out: $120 \times 7 = 840$ and $3 \times 7 = 21$, so $123 \times 7 = 861$.

Conclusion
The table of 123 stops feeling large once you split it into $100 + 20 + 3$ and add the three parts, checked by the units-digit cycle and the digit-sum rule. Learn the pattern, not the list, and any row is yours to rebuild.
