Their least common multiple (LCM).
Yes - if two numbers share no common factors (besides 1) the least common multiple will be the product of the numbers.
7, 14 and 28
These numbers do not share any common factors hence the least common multiple is the product-24.
A Common Multiple
10440 I think you mean lowest common multiple. 145 and 72 do not share any common factors, so the lowest common multiple is simply the product of the two numbers.
a common multiple. eg. 4 is a common multiple of 12 and 16.
Well, honey, the least common multiple of 5 and 31 is simply the product of the two numbers since they are already prime and don't share any common factors. So, the least common multiple of 5 and 31 is 155. Easy peasy lemon squeezy!
Well, darling, any pair of numbers that are multiples of 10 would work just fine. For example, 10 and 20, or 30 and 10. As long as 10 is the smallest number that both pairs can be evenly divided by, you're good to go. Math can be a real hoot sometimes, can't it?
63
take that number and plug it in and if the numbers are not decimals for both numbers then they share that multiple
yes, 3 and 6 have a common multiple of 18
