Least Common Multiple of 637,640

Least Common Multiple (LCM) of 637,640 is 407680

Given numbers has no common factors except 1. So, there LCM is their product i.e 407680

Least Common Multiple of 637,640 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 637,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(637,640) = 1

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

GCF(637,640) x common factors =1 x 1 = 1

LCM(637,640) = ( 637 × 640 ) / 1

LCM(637,640) = 407680 / 1

LCM(637,640) = 407680

∴ Least Common Multiple of 637,640 is 407680
