Lets's calculate LCM of 8,2,5,1,8,5,3,3,5,5

2 8, 2, 5, 1, 8, 5, 3, 3, 5, 5
2 4, 1, 5, 1, 4, 5, 3, 3, 5, 5
2 2, 1, 5, 1, 2, 5, 3, 3, 5, 5
3 1, 1, 5, 1, 1, 5, 3, 3, 5, 5
5 1, 1, 5, 1, 1, 5, 1, 1, 5, 5
1, 1, 1, 1, 1, 1, 1, 1, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 = 120

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/120

Therefore, the GCF of Fractions 63/8,49/2,83/5,71/1,947/8,10/5,31/3,939/3,23/5,69/5 is 1/120

Least Common Multiple of 8,2,5,1,8,5,3,3,5,5 with GCF Formula

Least Common Multiple of 8,2,5,1,8,5,3,3,5,5 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 8,2,5,1,8,5,3,3,5,5 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(8,2,5,1,8,5,3,3,5,5) = 1

common factors(in case of two or more numbers have common factors) = 6000

GCF(8,2,5,1,8,5,3,3,5,5) x common factors =1 x 6000 = 6000

LCM(8,2,5,1,8,5,3,3,5,5) = ( 8 × 2 × 5 × 1 × 8 × 5 × 3 × 3 × 5 × 5 ) / 6000

LCM(8,2,5,1,8,5,3,3,5,5) = 720000 / 6000

LCM(8,2,5,1,8,5,3,3,5,5) = 120
