Lets's calculate LCM of 15,81,71

3 15, 81, 71
5, 27, 71

∴ So the LCM of the given numbers is 3 x 5 x 27 x 71 = 28755

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/28755

Therefore, the GCF of Fractions 87/15,12/81,954/71 is 3/28755

Least Common Multiple of 15,81,71 with GCF Formula

Least Common Multiple of 15,81,71 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 15,81,71 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,81,71) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(15,81,71) x common factors =1 x 3 = 3

LCM(15,81,71) = ( 15 × 81 × 71 ) / 3

LCM(15,81,71) = 86265 / 3

LCM(15,81,71) = 28755
