Lets's calculate LCM of 80,49,207

Given numbers has no common factors except 1. So, there LCM is their product i.e 811440

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/811440

Therefore, the GCF of Fractions 48/80,138/49,491/207 is 1/811440

Least Common Multiple of 80,49,207 with GCF Formula

Least Common Multiple of 80,49,207 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 80,49,207 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,49,207) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(80,49,207) x common factors =1 x 1 = 1

LCM(80,49,207) = ( 80 × 49 × 207 ) / 1

LCM(80,49,207) = 811440 / 1

LCM(80,49,207) = 811440
