LCM of 70, 42, 14, 921

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 70,42,14,921

Least Common Multiple (LCM) of 70,42,14,921 is 64470

2 70, 42, 14, 921
3 35, 21, 7, 921
7 35, 7, 7, 307
5, 1, 1, 307

∴ So the LCM of the given numbers is 2 x 3 x 7 x 5 x 1 x 1 x 307 = 64470

Least Common Multiple of 70,42,14,921 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 70,42,14,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,42,14,921) = 1

common factors(in case of two or more numbers have common factors) = 588

GCF(70,42,14,921) x common factors =1 x 588 = 588

LCM(70,42,14,921) = ( 70 × 42 × 14 × 921 ) / 588

LCM(70,42,14,921) = 37908360 / 588

LCM(70,42,14,921) = 64470

∴ Least Common Multiple of 70,42,14,921 is 64470
