Least Common Multiple of 3920,5457

Least Common Multiple (LCM) of 3920,5457 is 21391440

Given numbers has no common factors except 1. So, there LCM is their product i.e 21391440

Least Common Multiple of 3920,5457 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 3920,5457 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3920,5457) = 1

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

GCF(3920,5457) x common factors =1 x 1 = 1

LCM(3920,5457) = ( 3920 × 5457 ) / 1

LCM(3920,5457) = 21391440 / 1

LCM(3920,5457) = 21391440

∴ Least Common Multiple of 3920,5457 is 21391440
