The least common multiple of two numbers is the product of those two numbers divided by their greatest common factor. It the two numbers are coprime (or relatively prime), their greatest common factor is 1. Therefore, their least common multiple is a x b ÷ GCF (of a and b) = a x b ÷ 1 = a x b. The least common multiple of two coprime numbers is the numbers multiplied together.

42. The numbers are coprime so their lowest common multiple is their multiple.

The least common multiple of 13 and 20 is 260.

Since the two numbers are coprime, 19*30 = 570

Since the two numbers are coprime, LCM(95, 84) = 7980

Since the two numbers are coprime, LCM(65, 49) = 65*49 = 3185

It would be a multiple. The word "LEAST" (in Least Common Multiple) is a superlative adjective and that means there can be only one. The result would be a least common multiple only if every pair of the numbers were coprime.

The two numbers are coprime so their LCM is their product = 9*17 = 153

The least common multiple is one of the numbers when one of the numbers is a multiple of the other.

All numbers with a least common multiple, have that multiple as a factor.

The least common multiple of the numbers 2,357 and 11 is 25,927.The least common multiple of the numbers 23, 57 and 11 is 14,421.

To find the least common multiple, you have to have at least 2 numbers.
