So the greatest common factor 92,57,15,18 is 1.

Lets's calculate LCM of 95,38,65,78

2 95, 38, 65, 78
5 95, 19, 65, 39
13 19, 19, 13, 39
19 19, 19, 1, 3
1, 1, 1, 3

∴ So the LCM of the given numbers is 2 x 5 x 13 x 19 x 1 x 1 x 1 x 3 = 7410

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7410

Therefore, the GCF of Fractions 92/95,57/38,15/65,18/78 is 1/7410

Least Common Multiple of 95,38,65,78 with GCF Formula

Least Common Multiple of 95,38,65,78 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 95,38,65,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(95,38,65,78) = 1

common factors(in case of two or more numbers have common factors) = 2470

GCF(95,38,65,78) x common factors =1 x 2470 = 2470

LCM(95,38,65,78) = ( 95 × 38 × 65 × 78 ) / 2470

LCM(95,38,65,78) = 18302700 / 2470

LCM(95,38,65,78) = 7410
