So the greatest common factor 48,28,61,91 is 1.

Lets's calculate LCM of 50,40,12,166

2 50, 40, 12, 166
2 25, 20, 6, 83
5 25, 10, 3, 83
5, 2, 3, 83

∴ So the LCM of the given numbers is 2 x 2 x 5 x 5 x 2 x 3 x 83 = 49800

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/49800

Therefore, the GCF of Fractions 48/50,28/40,61/12,91/166 is 1/49800

Least Common Multiple of 50,40,12,166 with GCF Formula

Least Common Multiple of 50,40,12,166 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 50,40,12,166 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(50,40,12,166) = 2

common factors(in case of two or more numbers have common factors) = 40

GCF(50,40,12,166) x common factors =2 x 40 = 80

LCM(50,40,12,166) = ( 50 × 40 × 12 × 166 ) / 80

LCM(50,40,12,166) = 3984000 / 80

LCM(50,40,12,166) = 49800
