Yes. Any pair of numbers has an infinite number of common multiples.
Because the common multiples of any two or more numbers are infinite.
6 and 9 are one pair of numbers with a common multiple of 18. Another pair are 9 and 18.
when one of the numbers is a multiple of the other, or when the other number is one.
Select ALL pairs of numbers that have a least common multiple of 30
12 and 24 is one such pair.
Because any multiple cam be multiplied. A common multiple of 3 and 6 is 12. That means that every multiple of 12 also has 3 and 6 as factors.
Only if the magnitudes of two numbers are the same.
There is no greatest common multiple of these numbers... or indeed of any pair of numbers. Once you get a common multiple, you can multiply that by any integer, as large as you want, to get a larger common multiple.
10 and 35
36 and 72
75 and 150, among others.
16 and 32
2 and 13
How about: 3 and 4
When one of the numbers is a multiple of the other, the greater is the LCM and the lesser is the GCF of that set.
They are 7 and 5
4 and 6 are one pair of numbers with an LCM of 12.
