It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
10 and 35 2 and 70
4 and 9, 12 and 18
18 and 36 12 and 36
20 and 30 15 and 60
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.

Two pairs of numbers with 105 as their least common multiple are (15, 105) and (21, 105). This means that both pairs of numbers are multiples of 105 and their only common multiple is 105. The least common multiple is the smallest number that both numbers can divide evenly into.

Select ALL pairs of numbers that have a least common multiple of 30
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.
