What are the common multiples of 84 and 16?

Common multiples of 84 and 16 are numbers that both 84 and 16 can be divided into evenly with no remainder.

To find the common multiples of 84 and 16, we compare the list of multiples of 84 with the list of multiples of 16 to see what they have in common.

To create a list of multiples of 84, we multiply 84 by 1, 84 by 2, and so on like this:

84 x 1 = 84
84 x 2 = 168
84 x 3 = 252
84 x 4 = 336
...

Similarly, to create a list of multiples of 16, we multiply 16 by 1, 16 by 2, and so on like this:

16 x 1 = 16
16 x 2 = 32
16 x 3 = 48
16 x 4 = 64
...

When we compare the two lists to see what they have in common, we get the answer to "What are the common multiples of 84 and 16?"

336, 672, 1008, 1344, etc.

Since 336 is the first number they have in common, 336 is the least common multiple of 84 and 16.

Note: Our lists are shortened because they go on forever, but can you see the pattern when you look at the answer in green above? The common multiples are in intervals of 336 (the least common multiple), so you can continue the green list above with more common multiples of 84 and 16 by simply adding 336 to the last number on the list.
