So the greatest common factor 80,54,28,80 is 2.

Lets's calculate LCM of 39,78,52,948

2 39, 78, 52, 948
2 39, 39, 26, 474
3 39, 39, 13, 237
13 13, 13, 13, 79
1, 1, 1, 79

∴ So the LCM of the given numbers is 2 x 2 x 3 x 13 x 1 x 1 x 1 x 79 = 12324

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/12324

Least Common Multiple of 39,78,52,948 with GCF Formula

Least Common Multiple of 39,78,52,948 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 39,78,52,948 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,78,52,948) = 1

common factors(in case of two or more numbers have common factors) = 12168

GCF(39,78,52,948) x common factors =1 x 12168 = 12168

LCM(39,78,52,948) = ( 39 × 78 × 52 × 948 ) / 12168

LCM(39,78,52,948) = 149958432 / 12168

LCM(39,78,52,948) = 12324
