LCM of:

Least Common Multiple of 21,85,43,872

Least Common Multiple (LCM) of 21,85,43,872 is 66930360

Given numbers has no common factors except 1. So, there LCM is their product i.e 66930360

Least Common Multiple of 21,85,43,872 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 21,85,43,872 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,85,43,872) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(21,85,43,872) x common factors =1 x 1 = 1

LCM(21,85,43,872) = ( 21 × 85 × 43 × 872 ) / 1

LCM(21,85,43,872) = 66930360 / 1

LCM(21,85,43,872) = 66930360

∴ Least Common Multiple of 21,85,43,872 is 66930360
