LCM of 56, 20, 85, 724

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 56,20,85,724

Least Common Multiple (LCM) of 56,20,85,724 is 861560

2 56, 20, 85, 724
2 28, 10, 85, 362
5 14, 5, 85, 181
14, 1, 17, 181

∴ So the LCM of the given numbers is 2 x 2 x 5 x 14 x 1 x 17 x 181 = 861560

Least Common Multiple of 56,20,85,724 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 56,20,85,724 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,20,85,724) = 1

common factors(in case of two or more numbers have common factors) = 80

GCF(56,20,85,724) x common factors =1 x 80 = 80

LCM(56,20,85,724) = ( 56 × 20 × 85 × 724 ) / 80

LCM(56,20,85,724) = 68924800 / 80

LCM(56,20,85,724) = 861560

∴ Least Common Multiple of 56,20,85,724 is 861560
