Greatest Common Factor

We found the factors 68,72,396 . The biggest common factor number is the GCF number.
So the greatest common factor 68,72,396 is 4.

Lets's calculate LCM of 36,71,83

Given numbers has no common factors except 1. So, there LCM is their product i.e 212148

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/212148

Therefore, the GCF of Fractions 68/36,72/71,396/83 is 4/212148

Least Common Multiple of 36,71,83 with GCF Formula

Least Common Multiple of 36,71,83 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 36,71,83 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(36,71,83) = 1

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

GCF(36,71,83) x common factors =1 x 1 = 1

LCM(36,71,83) = ( 36 × 71 × 83 ) / 1

LCM(36,71,83) = 212148 / 1

LCM(36,71,83) = 212148
