Least Common Multiple of 57,19,87,720

Least Common Multiple (LCM) of 57,19,87,720 is 396720

3	57, 19, 87, 720
19	19, 19, 29, 240
	1, 1, 29, 240

∴ So the LCM of the given numbers is 3 x 19 x 1 x 1 x 29 x 240 = 396720

Least Common Multiple of 57,19,87,720 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 57,19,87,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(57,19,87,720) = 1

common factors(in case of two or more numbers have common factors) = 171

GCF(57,19,87,720) x common factors =1 x 171 = 171

LCM(57,19,87,720) = ( 57 × 19 × 87 × 720 ) / 171

LCM(57,19,87,720) = 67839120 / 171

LCM(57,19,87,720) = 396720

∴ Least Common Multiple of 57,19,87,720 is 396720
