Select ALL pairs of numbers that have a least common multiple of 30
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.
7 and 15 35 and 3
16 and 25 23 and 47 27 and 50
3 and 8
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.

Pick any two numbers. All pairs of numbers have an LCM.
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
