So the greatest common factor 47,32,20,309 is 1.

Lets's calculate LCM of 62,12,80,80

2 62, 12, 80, 80
2 31, 6, 40, 40
2 31, 3, 20, 20
2 31, 3, 10, 10
5 31, 3, 5, 5
31, 3, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 31 x 3 x 1 x 1 = 7440

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7440

Therefore, the GCF of Fractions 47/62,32/12,20/80,309/80 is 1/7440

Least Common Multiple of 62,12,80,80 with GCF Formula

Least Common Multiple of 62,12,80,80 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 62,12,80,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(62,12,80,80) = 2

common factors(in case of two or more numbers have common factors) = 320

GCF(62,12,80,80) x common factors =2 x 320 = 640

LCM(62,12,80,80) = ( 62 × 12 × 80 × 80 ) / 640

LCM(62,12,80,80) = 4761600 / 640

LCM(62,12,80,80) = 7440
