Least Common Multiple of 40/416,86/640,272/905

Given numbers are 40/416,86/640,272/905

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 40,86,272

Least Common Multiple of Numerators i.e. LCM of 40,86,272 is 58480.

GCF of Denominators means GCF of 416,640,905 as per the given fractions.

GCF of 416,640,905 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 40,86,272

LCM of Fractions 40/416,86/640,272/905 is 58480

2 40, 86, 272
2 20, 43, 136
2 10, 43, 68
5, 43, 34

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 43 x 34 = 58480

Least Common Multiple of 40,86,272 with GCF Formula

Least Common Multiple of 40,86,272 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 40,86,272 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,86,272) = 2

common factors(in case of two or more numbers have common factors) = 8

GCF(40,86,272) x common factors =2 x 8 = 16

LCM(40,86,272) = ( 40 × 86 × 272 ) / 16

LCM(40,86,272) = 935680 / 16

LCM(40,86,272) = 58480


Lets's calculate GCF of 416,640,905

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 58480/1

Therefore the LCM of Fractions 40/416,86/640,272/905 is 58480
