Lets's calculate LCM of 70,15,717

3 70, 15, 717
5 70, 5, 239
14, 1, 239

∴ So the LCM of the given numbers is 3 x 5 x 14 x 1 x 239 = 50190

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/50190

Therefore, the GCF of Fractions 91/70,23/15,272/717 is 1/50190

Least Common Multiple of 70,15,717 with GCF Formula

Least Common Multiple of 70,15,717 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 70,15,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,15,717) = 1

common factors(in case of two or more numbers have common factors) = 15

GCF(70,15,717) x common factors =1 x 15 = 15

LCM(70,15,717) = ( 70 × 15 × 717 ) / 15

LCM(70,15,717) = 752850 / 15

LCM(70,15,717) = 50190
