What are the common multiples of 65 and 79?

Common multiples of 65 and 79 are numbers that both 65 and 79 can be divided into evenly with no remainder.

To find the common multiples of 65 and 79, we compare the list of multiples of 65 with the list of multiples of 79 to see what they have in common.

To create a list of multiples of 65, we multiply 65 by 1, 65 by 2, and so on like this:

65 x 1 = 65
65 x 2 = 130
65 x 3 = 195
65 x 4 = 260
...

Similarly, to create a list of multiples of 79, we multiply 79 by 1, 79 by 2, and so on like this:

79 x 1 = 79
79 x 2 = 158
79 x 3 = 237
79 x 4 = 316
...

When we compare the two lists to see what they have in common, we get the answer to "What are the common multiples of 65 and 79?"

5135, 10270, 15405, 20540, etc.

Since 5135 is the first number they have in common, 5135 is the least common multiple of 65 and 79.

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 5135 (the least common multiple), so you can continue the green list above with more common multiples of 65 and 79 by simply adding 5135 to the last number on the list.
