So the greatest common factor 54,15,77,980 is 1.

Lets's calculate LCM of 10,39,78,81

2 10, 39, 78, 81
3 5, 39, 39, 81
13 5, 13, 13, 27
5, 1, 1, 27

∴ So the LCM of the given numbers is 2 x 3 x 13 x 5 x 1 x 1 x 27 = 10530

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10530

Least Common Multiple of 10,39,78,81 with GCF Formula

Least Common Multiple of 10,39,78,81 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 10,39,78,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(10,39,78,81) = 1

common factors(in case of two or more numbers have common factors) = 234

GCF(10,39,78,81) x common factors =1 x 234 = 234

LCM(10,39,78,81) = ( 10 × 39 × 78 × 81 ) / 234

LCM(10,39,78,81) = 2464020 / 234

LCM(10,39,78,81) = 10530
