Best Answer

The lowest common multiple of 7 and 9 is 63.

Here's how to work it out:

Multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...

Multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...

To find the lowest common multiple you look and find the smallest number that is a multiple of both numbers (in your case 7 and 9). So, in this case the lowest multiple they both have in common is 63.

7 and 9 have no common factors (7 is a Prime number, and 9 is not a multiple of 7). Therefore, the smallest common multiple is the product of both.

63 is the LCM of 9 and 7.

LCM(9, 7) = 63

The least common multiple is 63.
