CoachThe 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.
