So the greatest common factor 76,42,81,391 is 1.

Lets's calculate LCM of 60,72,43,91

2 60, 72, 43, 91
2 30, 36, 43, 91
3 15, 18, 43, 91
5, 6, 43, 91

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 6 x 43 x 91 = 1408680

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1408680

Least Common Multiple of 60,72,43,91 with GCF Formula

Least Common Multiple of 60,72,43,91 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 60,72,43,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(60,72,43,91) = 1

common factors(in case of two or more numbers have common factors) = 12

GCF(60,72,43,91) x common factors =1 x 12 = 12

LCM(60,72,43,91) = ( 60 × 72 × 43 × 91 ) / 12

LCM(60,72,43,91) = 16904160 / 12

LCM(60,72,43,91) = 1408680
