Least Common Multiple of 20,77,141

Least Common Multiple (LCM) of 20,77,141 is 217140

Given numbers has no common factors except 1. So, there LCM is their product i.e 217140

Least Common Multiple of 20,77,141 with GCF Formula

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

We need to calculate greatest common factor of 20,77,141 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,77,141) = 1

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

GCF(20,77,141) x common factors =1 x 1 = 1

LCM(20,77,141) = ( 20 × 77 × 141 ) / 1

LCM(20,77,141) = 217140 / 1

LCM(20,77,141) = 217140

∴ Least Common Multiple of 20,77,141 is 217140
