LCM of:

Least Common Multiple of 56,90,20,671

Least Common Multiple (LCM) of 56,90,20,671 is 1690920

2 56, 90, 20, 671
2 28, 45, 10, 671
5 14, 45, 5, 671
14, 9, 1, 671

∴ So the LCM of the given numbers is 2 x 2 x 5 x 14 x 9 x 1 x 671 = 1690920

Least Common Multiple of 56,90,20,671 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 56,90,20,671 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,90,20,671) = 1

common factors(in case of two or more numbers have common factors) = 40

GCF(56,90,20,671) x common factors =1 x 40 = 40

LCM(56,90,20,671) = ( 56 × 90 × 20 × 671 ) / 40

LCM(56,90,20,671) = 67636800 / 40

LCM(56,90,20,671) = 1690920

∴ Least Common Multiple of 56,90,20,671 is 1690920
