Lets's calculate LCM of 72,88,528

2 72, 88, 528
2 36, 44, 264
2 18, 22, 132
3 9, 11, 66
11 3, 11, 22
3, 1, 2

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 11 x 3 x 1 x 2 = 1584

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1584

Least Common Multiple of 72,88,528 with GCF Formula

Least Common Multiple of 72,88,528 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 72,88,528 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,88,528) = 8

common factors(in case of two or more numbers have common factors) = 264

GCF(72,88,528) x common factors =8 x 264 = 2112

LCM(72,88,528) = ( 72 × 88 × 528 ) / 2112

LCM(72,88,528) = 3345408 / 2112

LCM(72,88,528) = 1584
