Greatest Common Factor

We found the factors 510,990 . The biggest common factor number is the GCF number.
So the greatest common factor 510,990 is 30.

Lets's calculate LCM of 77,807

Given numbers has no common factors except 1. So, there LCM is their product i.e 62139

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/62139

Therefore, the GCF of Fractions 510/77,990/807 is 30/62139

Least Common Multiple of 77,807 with GCF Formula

Least Common Multiple of 77,807 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 77,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,807) = 1

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

GCF(77,807) x common factors =1 x 1 = 1

LCM(77,807) = ( 77 × 807 ) / 1

LCM(77,807) = 62139 / 1

LCM(77,807) = 62139
