Lets's calculate LCM of 76,72,72,561

2 76, 72, 72, 561
2 38, 36, 36, 561
2 19, 18, 18, 561
3 19, 9, 9, 561
3 19, 3, 3, 187
19, 1, 1, 187

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 19 x 1 x 1 x 187 = 255816

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/255816

Least Common Multiple of 76,72,72,561 with GCF Formula

Least Common Multiple of 76,72,72,561 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 76,72,72,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(76,72,72,561) = 1

common factors(in case of two or more numbers have common factors) = 864

GCF(76,72,72,561) x common factors =1 x 864 = 864

LCM(76,72,72,561) = ( 76 × 72 × 72 × 561 ) / 864

LCM(76,72,72,561) = 221025024 / 864

LCM(76,72,72,561) = 255816
