So the greatest common factor 20,28,179 is 1.

Lets's calculate LCM of 50,85,35

5 50, 85, 35
10, 17, 7

∴ So the LCM of the given numbers is 5 x 10 x 17 x 7 = 5950

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5950

Therefore, the GCF of Fractions 20/50,28/85,179/35 is 1/5950

Least Common Multiple of 50,85,35 with GCF Formula

Least Common Multiple of 50,85,35 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 50,85,35 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(50,85,35) = 5

common factors(in case of two or more numbers have common factors) = 5

GCF(50,85,35) x common factors =5 x 5 = 25

LCM(50,85,35) = ( 50 × 85 × 35 ) / 25

LCM(50,85,35) = 148750 / 25

LCM(50,85,35) = 5950
