Lets's calculate LCM of 4,8,7,2,2,7,5,6,7,4

2 4, 8, 7, 2, 2, 7, 5, 6, 7, 4
2 2, 4, 7, 1, 1, 7, 5, 3, 7, 2
7 1, 1, 7, 1, 1, 7, 5, 3, 7, 2
1, 1, 1, 1, 1, 1, 5, 3, 1, 2

∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 1 x 1 x 1 x 1 x 1 x 5 x 3 x 1 x 2 = 840

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/840

Therefore, the GCF of Fractions 50/4,67/8,17/7,37/2,638/2,81/7,70/5,709/6,43/7,99/4 is 1/840

Least Common Multiple of 4,8,7,2,2,7,5,6,7,4 with GCF Formula

Least Common Multiple of 4,8,7,2,2,7,5,6,7,4 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 4,8,7,2,2,7,5,6,7,4 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(4,8,7,2,2,7,5,6,7,4) = 1

common factors(in case of two or more numbers have common factors) = 6272

GCF(4,8,7,2,2,7,5,6,7,4) x common factors =1 x 6272 = 6272

LCM(4,8,7,2,2,7,5,6,7,4) = ( 4 × 8 × 7 × 2 × 2 × 7 × 5 × 6 × 7 × 4 ) / 6272

LCM(4,8,7,2,2,7,5,6,7,4) = 5268480 / 6272

LCM(4,8,7,2,2,7,5,6,7,4) = 840
