Multiplication Table Of 28
The table of 28 is the list of products you get when you multiply 28 by each whole number in turn. Because $28 = 2 \times 14$ and $28 = 4 \times 7$, every row can be reached from a smaller table you already know.

What Is The Table Of 28 In Words?
Reading each row aloud builds the rhythm before the numbers settle in.
One times 28 is 28
Two times 28 is 56
Three times 28 is 84
Four times 28 is 112
Five times 28 is 140
Six times 28 is 168
Seven times 28 is 196
Eight times 28 is 224
Nine times 28 is 252
Ten times 28 is 280
What Is The 28 Times Table?
The 28 times table is repeated addition of 28. Each row adds one more group of twenty-eight, so the table answers "how much is twenty-eight, added to itself, again and again?"
Built from the ground up, the ladder looks like this:
$28$
$28 + 28 = 56$
$28 + 28 + 28 = 84$
$28 + 28 + 28 + 28 = 112$
Multiplication is the shortcut for this stacking, which is why $28 \times 4$ and "four twenty-eights added together" both give 112.
What Are The Multiples Of 28?
The multiples of 28 are the numbers you reach by skip-counting in twenty-eights. The first twenty multiples are:
28, 56, 84, 112, 140, 168, 196, 224, 252, 280, 308, 336, 364, 392, 420, 448, 476, 504, 532, 560.
Every entry in the table of 28 is a multiple of 28, and each is also a multiple of 14, of 7, of 4, and of 2. Because 28 is even, every product is even too, so any odd answer is a signal to check your work.
How To Learn The 28 Times Table (Patterns, Not Memorizing)
Bhanzu teaches the few patterns that generate a table rather than drilling its facts into recall, so a student can rebuild any row by reasoning and carry that number sense into algebra. The table of 28 is built from three smaller tables at once, so you rarely have to store a fact you can rebuild in a step or two.
Every pattern below comes from how 28 is composed: $28 = 2 \times 14$, $28 = 4 \times 7$, and $28 = 30 - 2$.
Pattern 1: Double the 14 times table. Because $28 = 2 \times 14$, every multiple of 28 is double the matching multiple of 14. For $28 \times 6$: $14 \times 6 = 84$, doubled is 168. Learn the 14 times table and this one follows.
Pattern 2: Double the 7 table, then double again. Because $28 = 4 \times 7$, you can reach a row from the 7 times table by doubling twice: for $28 \times 3$, take $7 \times 3 = 21$, double to 42, double again to 84.
Pattern 3: Thirty times, then step back twice the multiplier. Because $28 = 30 - 2$, use $28k = 30k - 2k$. For $28 \times 5$: $30 \times 5 = 150$, then $150 - 10 = 140$.
Pattern 4: Split the multiplier by place value. For $28 \times 13$, read 13 as $10 + 3$, so $28 \times 13 = (28 \times 10) + (28 \times 3) = 280 + 84 = 364$ - the distributive idea you meet again as $28(10 + 3)$ in algebra.
How Do You Read And Use The Table Of 28?
Read each row left to right: $28 \times 6 = 168$ is "twenty-eight multiplied six times gives one hundred sixty-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 while doubling from the fourteens, then quiz yourself in a shuffled order so you are recalling facts rather than reciting a chant. The double-the-14 link is your safety net, so if a row slips, rebuild it from the fourteens.
Where Does The Table Of 28 Appear?
Twenty-eight is the length of February in a common year and the length of a lunar cycle, so the table of 28 counts weeks and cycles cleanly: 28 days is exactly 4 weeks, so 28 times a number of months of this length converts straight to days. It also shows up in pay and rosters built on 28-day cycles, and in any grid of 28 seats or tiles, where the multiples give running totals at a glance.
Solved Examples Of The Table Of 28
Example 1
What is $28 \times 6$?
Double the 14s: $14 \times 6 = 84$.
$84 \times 2 = 168$
Final answer: $28 \times 6 = 168$.
Example 2
A carton holds 28 bottles. How many bottles are in 9 cartons?
Wrong attempt. A rusher reads $28 \times 9$ as $28 \times 10 = 280$ and stops there.
Why it breaks. Nine cartons must hold less than ten cartons, so 280 overcounts by one whole carton of 28.
Correct. Take $28 \times 10 = 280$, then subtract one 28.
$280 - 28 = 252$
Final answer: 252 bottles.
Example 3
Find $28 \times 13$.
Split it: $28 \times 10 = 280$ and $28 \times 3 = 84$.
$280 + 84 = 364$
Final answer: $28 \times 13 = 364$.
Example 4
$28 \times {?} = 420$.
Divide to find the missing factor: $420 \div 28 = 15$.
Final answer: $28 \times 15 = 420$.
Example 5
February has 28 days. How many days are in 4 such months?
Double the 14s twice, or read it off: $28 \times 4 = 112$.
Final answer: 112 days.
What Are Common Mistakes With The Table Of 28?
Mistake 1: Doubling the 14s only once when the multiplier changes
Where it slips in: Doubling a single 14-fact but forgetting the multiplier must stay the same on both sides.
Don't do this: Writing $28 \times 6$ as $14 \times 12 = 168$ by "moving the double onto the 6."
The correct way: Keep the multiplier fixed: $14 \times 6 = 84$, then double the product to 168. (The answer matches here, but the habit breaks on other rows.)
Mistake 2: Landing on an odd product
Where it slips in: Adding 28 across rows and slipping a digit, so an answer comes out odd.
Don't do this: Writing $28 \times 7 = 195$.
The correct way: Every multiple of 28 is even, so 195 must be wrong. Recompute: $28 \times 7 = 196$.

Conclusion
The table of 28 is easiest to hold not as twenty separate rows but as the 14 times table doubled, backed up by its links to the 7s and to 30-minus-2. Read the chart, check that every answer is even, and rebuild any row you forget from the fourteens.
