∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 3 x 1 x 11 x 53 = 209880

Least Common Multiple of 72,40,55,636 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 72,40,55,636 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,40,55,636) = 1

common factors(in case of two or more numbers have common factors) = 480

GCF(72,40,55,636) x common factors =1 x 480 = 480

LCM(72,40,55,636) = ( 72 × 40 × 55 × 636 ) / 480

LCM(72,40,55,636) = 100742400 / 480

LCM(72,40,55,636) = 209880

∴ Least Common Multiple of 72,40,55,636 is 209880
