∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 79 x 1 x 4 x 3 = 199080

Least Common Multiple of 79,42,40,630 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 79,42,40,630 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(79,42,40,630) = 1

common factors(in case of two or more numbers have common factors) = 420

GCF(79,42,40,630) x common factors =1 x 420 = 420

LCM(79,42,40,630) = ( 79 × 42 × 40 × 630 ) / 420

LCM(79,42,40,630) = 83613600 / 420

LCM(79,42,40,630) = 199080

∴ Least Common Multiple of 79,42,40,630 is 199080
