If two composite numbers are relatively prime and their least common multiple is 126, find the sum of these two numbers.

Hi mworkhard222

 

If two composite numbers are relatively prime and their least common multiple is 126, find the sum of these two numbers.

 

factor(126) = (2*3^2)*7 = 2*7*3*3

 

the two 3's must go together, 9  so the other number must be 14  They are the only composite numbers that work.
