What is a Lowest Common Multiple? Consider the numbers 2 and 5 The lowest common multiple is the smallest number which is the multiple of both. Multiples of 2 are: 2, 4, 6, 8, 10, 12, 14, … Multiples of 5 are: 5, 10, 15, 20, 25, … Which is the smallest number that occurs in BOTH lists? This is the LOWEST COMMON MULITPLE.

What is the LOWEST COMMON MULTIPLE of: 2 and 7 3 and 7 5 and 3 5 and 7
