Lets's calculate LCM of 50,20,921

2 50, 20, 921
5 25, 10, 921
5, 2, 921

∴ So the LCM of the given numbers is 2 x 5 x 5 x 2 x 921 = 92100

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/92100

Therefore, the GCF of Fractions 69/50,81/20,454/921 is 1/92100

Least Common Multiple of 50,20,921 with GCF Formula

Least Common Multiple of 50,20,921 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 50,20,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(50,20,921) = 1

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

GCF(50,20,921) x common factors =1 x 10 = 10

LCM(50,20,921) = ( 50 × 20 × 921 ) / 10

LCM(50,20,921) = 921000 / 10

LCM(50,20,921) = 92100
