LCM of:

Least Common Multiple of 420/126,324/712

Given numbers are 420/126,324/712

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 420,324

Least Common Multiple of Numerators i.e. LCM of 420,324 is 11340.

GCF of Denominators means GCF of 126,712 as per the given fractions.

GCF of 126,712 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 420,324

LCM of Fractions 420/126,324/712 is 5670

2 420, 324
2 210, 162
3 105, 81
35, 27

∴ So the LCM of the given numbers is 2 x 2 x 3 x 35 x 27 = 11340

Least Common Multiple of 420,324 with GCF Formula

Least Common Multiple of 420,324 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 420,324 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,324) = 12

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

GCF(420,324) x common factors =12 x 1 = 12

LCM(420,324) = ( 420 × 324 ) / 12

LCM(420,324) = 136080 / 12

LCM(420,324) = 11340


Lets's calculate GCF of 126,712

2 126, 712
63, 356

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11340/2

Therefore the LCM of Fractions 420/126,324/712 is 5670
