The way to work this out is to break the number down into its prime factors. In this case, 10 can be expressed as 2x5. Thus two numbers will have 10 as a common multiple if the only unique factors between them is a single 2 and a single 5. This can be achieved with the following pairs:
1 and 10
2 and 10
5 and 10
2 and 5

2 and 15 10 and 15
What is the common multiple of 120 and 149?
There are many common multiples of 120 and 149. A common multiple is simply a multiple of both numbers. The least common multiple is 120x149, since 149 is prime. (Note: this trick doesn't work on all pairs of number. Although the product is always a multiple, it's not the least common multiple.)
Are there any pairs of prime numbers that when multiplied do not make their least common multiple?
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
What pair of numbers has a least common multiple of 30?
Select ALL pairs of numbers that have a least common multiple of 30
What are 2 pairs of numbers with 105 as their least common multiple?
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.

How do you get two pair of numbers that have a least common multiple?
Pick any two numbers. All pairs of numbers have an LCM.
What does find three pairs of numbers for which the least common multiple equals the product of the two numbers mean?
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
