Lets's calculate LCM of 80,34,28,493

2 80, 34, 28, 493
2 40, 17, 14, 493
17 20, 17, 7, 493
20, 1, 7, 29

∴ So the LCM of the given numbers is 2 x 2 x 17 x 20 x 1 x 7 x 29 = 276080

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/276080

Therefore, the GCF of Fractions 55/80,71/34,99/28,62/493 is 1/276080

Least Common Multiple of 80,34,28,493 with GCF Formula

Least Common Multiple of 80,34,28,493 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 80,34,28,493 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,34,28,493) = 1

common factors(in case of two or more numbers have common factors) = 136

GCF(80,34,28,493) x common factors =1 x 136 = 136

LCM(80,34,28,493) = ( 80 × 34 × 28 × 493 ) / 136

LCM(80,34,28,493) = 37546880 / 136

LCM(80,34,28,493) = 276080
