Least Common Multiple of 1240,3987

Least Common Multiple (LCM) of 1240,3987 is 4943880

Given numbers has no common factors except 1. So, there LCM is their product i.e 4943880

Least Common Multiple of 1240,3987 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 1240,3987 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1240,3987) = 1

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

GCF(1240,3987) x common factors =1 x 1 = 1

LCM(1240,3987) = ( 1240 × 3987 ) / 1

LCM(1240,3987) = 4943880 / 1

LCM(1240,3987) = 4943880

∴ Least Common Multiple of 1240,3987 is 4943880
