Least Common Multiple of 468/21,896/26,781/40

Given numbers are 468/21,896/26,781/40

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 468,896,781

Least Common Multiple of Numerators i.e. LCM of 468,896,781 is 81873792.

GCF of Denominators means GCF of 21,26,40 as per the given fractions.

GCF of 21,26,40 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 468,896,781

LCM of Fractions 468/21,896/26,781/40 is 81873792

2 468, 896, 781
2 234, 448, 781
117, 224, 781

∴ So the LCM of the given numbers is 2 x 2 x 117 x 224 x 781 = 81873792

Least Common Multiple of 468,896,781 with GCF Formula

Least Common Multiple of 468,896,781 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 468,896,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(468,896,781) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(468,896,781) x common factors =1 x 4 = 4

LCM(468,896,781) = ( 468 × 896 × 781 ) / 4

LCM(468,896,781) = 327495168 / 4

LCM(468,896,781) = 81873792


Lets's calculate GCF of 21,26,40

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 81873792/1

Therefore the LCM of Fractions 468/21,896/26,781/40 is 81873792
