What are the common multiples of 70 and 99?

Common multiples of 70 and 99 are numbers that both 70 and 99 can be divided into evenly with no remainder.

To find the common multiples of 70 and 99, we compare the list of multiples of 70 with the list of multiples of 99 to see what they have in common.

To create a list of multiples of 70, we multiply 70 by 1, 70 by 2, and so on like this:

70 x 1 = 70
70 x 2 = 140
70 x 3 = 210
70 x 4 = 280
...

Similarly, to create a list of multiples of 99, we multiply 99 by 1, 99 by 2, and so on like this:

99 x 1 = 99
99 x 2 = 198
99 x 3 = 297
99 x 4 = 396
...

When we compare the two lists to see what they have in common, we get the answer to "What are the common multiples of 70 and 99?"

6930, 13860, 20790, 27720, etc.

Since 6930 is the first number they have in common, 6930 is the least common multiple of 70 and 99.

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 6930 (the least common multiple), so you can continue the green list above with more common multiples of 70 and 99 by simply adding 6930 to the last number on the list.
