Lets's calculate LCM of 70,37,380

2 70, 37, 380
5 35, 37, 190
7, 37, 38

∴ So the LCM of the given numbers is 2 x 5 x 7 x 37 x 38 = 98420

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/98420

Therefore, the GCF of Fractions 21/70,591/37,116/380 is 1/98420

Least Common Multiple of 70,37,380 with GCF Formula

Least Common Multiple of 70,37,380 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 70,37,380 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,37,380) = 1

common factors(in case of two or more numbers have common factors) = 10

GCF(70,37,380) x common factors =1 x 10 = 10

LCM(70,37,380) = ( 70 × 37 × 380 ) / 10

LCM(70,37,380) = 984200 / 10

LCM(70,37,380) = 98420
