13 - 26 - 39 - 52
There is an infinite number of common multiples for 13 and 17. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 13 and 17 is 221.
52 = 4 x 13 = 22 x 1381 = 9 x 9 = 34Since 52 and 81 do not have any common prime factor, then 52 x 81 = 4,212 is their LCM. So that the other multiples they have in common are all the multiples of 4,212.
The only multiples that go into 13 evenly are ' 1 ' (a multiple of ' 1 ') and 13 (a multiple of ' 1 ' and 13).
