LCM(20, 39, 73) = 56940

LCM of 20, 39, 73

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

LCM of:

Least Common Multiple of 20,39,73

Least Common Multiple (LCM) of 20,39,73 is 56940

Given numbers has no common factors except 1. So, there LCM is their product i.e 56940

Least Common Multiple of 20,39,73 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 20,39,73 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,39,73) = 1

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

GCF(20,39,73) x common factors =1 x 1 = 1

LCM(20,39,73) = ( 20 × 39 × 73 ) / 1

LCM(20,39,73) = 56940 / 1

LCM(20,39,73) = 56940

∴ Least Common Multiple of 20,39,73 is 56940
