We found the factors 8,8,14,81 . The biggest common factor number is the GCF number.
So the greatest common factor 8,8,14,81 is 1.

Lets's calculate LCM of 20,44,79,690

2 20, 44, 79, 690
2 10, 22, 79, 345
5 5, 11, 79, 345
1, 11, 79, 69

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 11 x 79 x 69 = 1199220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1199220

Therefore, the GCF of Fractions 8/20,8/44,14/79,81/690 is 1/1199220

Least Common Multiple of 20,44,79,690 with GCF Formula

Least Common Multiple of 20,44,79,690 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 20,44,79,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,44,79,690) = 1

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

GCF(20,44,79,690) x common factors =1 x 40 = 40

LCM(20,44,79,690) = ( 20 × 44 × 79 × 690 ) / 40

LCM(20,44,79,690) = 47968800 / 40

LCM(20,44,79,690) = 1199220
