What are the common multiples of 87 and 3?

Common multiples of 87 and 3 are numbers that both 87 and 3 can be divided into evenly with no remainder.

To find the common multiples of 87 and 3, we compare the list of multiples of 87 with the list of multiples of 3 to see what they have in common.

To create a list of multiples of 87, we multiply 87 by 1, 87 by 2, and so on like this:

87 x 1 = 87
87 x 2 = 174
87 x 3 = 261
87 x 4 = 348
...

Similarly, to create a list of multiples of 3, we multiply 3 by 1, 3 by 2, and so on like this:

3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
...

When we compare the two lists to see what they have in common, we get the answer to "What are the common multiples of 87 and 3?"

87, 174, 261, 348, etc.

Since 87 is the first number they have in common, 87 is the least common multiple of 87 and 3.

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 87 (the least common multiple), so you can continue the green list above with more common multiples of 87 and 3 by simply adding 87 to the last number on the list.
