12 and 18.12,24,36,48,60.18,36,54,72,90.
Two pairs of #'s with 10 as their least common multiple: 5x2 1x10
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
In that case, one of the numbers is a multiple of the other.
Pick any two numbers. All pairs of numbers have an LCM.
