Least Common Multiple of 126/19,640/66,400/945

Given numbers are 126/19,640/66,400/945

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 126,640,400

Least Common Multiple of Numerators i.e. LCM of 126,640,400 is 201600.

GCF of Denominators means GCF of 19,66,945 as per the given fractions.

GCF of 19,66,945 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 126,640,400

LCM of Fractions 126/19,640/66,400/945 is 201600

2 126, 640, 400
2 63, 320, 200
2 63, 160, 100
2 63, 80, 50
5 63, 40, 25
63, 8, 5

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 63 x 8 x 5 = 201600

Least Common Multiple of 126,640,400 with GCF Formula

Least Common Multiple of 126,640,400 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 126,640,400 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(126,640,400) = 2

common factors(in case of two or more numbers have common factors) = 80

GCF(126,640,400) x common factors =2 x 80 = 160

LCM(126,640,400) = ( 126 × 640 × 400 ) / 160

LCM(126,640,400) = 32256000 / 160

LCM(126,640,400) = 201600


Lets's calculate GCF of 19,66,945

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 201600/1

Therefore the LCM of Fractions 126/19,640/66,400/945 is 201600
