LCM of:

Least Common Multiple of 21,20,913

Least Common Multiple (LCM) of 21,20,913 is 383460

Given numbers has no common factors except 1. So, there LCM is their product i.e 383460

Least Common Multiple of 21,20,913 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 21,20,913 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,20,913) = 1

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

GCF(21,20,913) x common factors =1 x 1 = 1

LCM(21,20,913) = ( 21 × 20 × 913 ) / 1

LCM(21,20,913) = 383460 / 1

LCM(21,20,913) = 383460

∴ Least Common Multiple of 21,20,913 is 383460
