What are the common multiples of 91 and 18?

Common multiples of 91 and 18 are numbers that both 91 and 18 can be divided into evenly with no remainder.

To find the common multiples of 91 and 18, we compare the list of multiples of 91 with the list of multiples of 18 to see what they have in common.

To create a list of multiples of 91, we multiply 91 by 1, 91 by 2, and so on like this:

91 x 1 = 91
91 x 2 = 182
91 x 3 = 273
91 x 4 = 364
...

Similarly, to create a list of multiples of 18, we multiply 18 by 1, 18 by 2, and so on like this:

18 x 1 = 18
18 x 2 = 36
18 x 3 = 54
18 x 4 = 72
...

When we compare the two lists to see what they have in common, we get the answer to "What are the common multiples of 91 and 18?"

1638, 3276, 4914, 6552, etc.

Since 1638 is the first number they have in common, 1638 is the least common multiple of 91 and 18.

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 1638 (the least common multiple), so you can continue the green list above with more common multiples of 91 and 18 by simply adding 1638 to the last number on the list.
