Lets's calculate LCM of 77,262

Given numbers has no common factors except 1. So, there LCM is their product i.e 20174

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/20174

Therefore, the GCF of Fractions 813/77,981/262 is 3/20174

Least Common Multiple of 77,262 with GCF Formula

Least Common Multiple of 77,262 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 77,262 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,262) = 1

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

GCF(77,262) x common factors =1 x 1 = 1

LCM(77,262) = ( 77 × 262 ) / 1

LCM(77,262) = 20174 / 1

LCM(77,262) = 20174
