What is the least common multiple of 36 and 80?

Answer 1

Method to find LCM of two numbers a & b:

1- Find GCF of a & b.

2- Find product of a & b.

3- Divide the result obtained in step 2 by the GCF. The result is LCM of a & b.

1- GCF of 36 & 80 = ?

Prime factorization of 36 = 2x2x3x3

Prime factorization of 80 = 2x2x2x2x2x5

GCF = 4

2- Product of 36 & 80 = 2880

3- LCM = 2880/4 = 720

Answer 2

720
