LCM of:

Least Common Multiple of 399/85,172/7211

Given numbers are 399/85,172/7211

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 399,172

Least Common Multiple of Numerators i.e. LCM of 399,172 is 68628.

GCF of Denominators means GCF of 85,7211 as per the given fractions.

GCF of 85,7211 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 399,172

LCM of Fractions 399/85,172/7211 is 68628

Given numbers has no common factors except 1. So, there LCM is their product i.e 68628

Least Common Multiple of 399,172 with GCF Formula

Least Common Multiple of 399,172 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 399,172 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(399,172) = 1

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

GCF(399,172) x common factors =1 x 1 = 1

LCM(399,172) = ( 399 × 172 ) / 1

LCM(399,172) = 68628 / 1

LCM(399,172) = 68628


Lets's calculate GCF of 85,7211

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 68628/1

Therefore the LCM of Fractions 399/85,172/7211 is 68628
