GCF of Denominators means GCF of 78,2818 as per the given fractions.

GCF of 78,2818 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 991,689

LCM of Fractions 991/78,689/2818 is 682799/2

Given numbers has no common factors except 1. So, there LCM is their product i.e 682799

Least Common Multiple of 991,689 with GCF Formula

Least Common Multiple of 991,689 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 991,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(991,689) = 1

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

GCF(991,689) x common factors =1 x 1 = 1

LCM(991,689) = ( 991 × 689 ) / 1

LCM(991,689) = 682799 / 1

LCM(991,689) = 682799


Lets's calculate GCF of 78,2818

2 78, 2818
39, 1409

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 682799/2

Therefore the LCM of Fractions 991/78,689/2818 is 682799/2
