Lets's calculate LCM of 75,78,97,970

2 75, 78, 97, 970
3 75, 39, 97, 485
5 25, 13, 97, 485
97 5, 13, 97, 97
5, 13, 1, 1

∴ So the LCM of the given numbers is 2 x 3 x 5 x 97 x 5 x 13 x 1 x 1 = 189150

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/189150

Least Common Multiple of 75,78,97,970 with GCF Formula

Least Common Multiple of 75,78,97,970 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 75,78,97,970 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(75,78,97,970) = 1

common factors(in case of two or more numbers have common factors) = 2910

GCF(75,78,97,970) x common factors =1 x 2910 = 2910

LCM(75,78,97,970) = ( 75 × 78 × 97 × 970 ) / 2910

LCM(75,78,97,970) = 550426500 / 2910

LCM(75,78,97,970) = 189150
