Least Common Multiple of 400/58,251/40,840/87

Given numbers are 400/58,251/40,840/87

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 400,251,840

Least Common Multiple of Numerators i.e. LCM of 400,251,840 is 2108400.

GCF of Denominators means GCF of 58,40,87 as per the given fractions.

GCF of 58,40,87 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 400,251,840

LCM of Fractions 400/58,251/40,840/87 is 2108400

2 400, 251, 840
2 200, 251, 420
2 100, 251, 210
5 50, 251, 105
10, 251, 21

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 10 x 251 x 21 = 2108400

Least Common Multiple of 400,251,840 with GCF Formula

Least Common Multiple of 400,251,840 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 400,251,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(400,251,840) = 1

common factors(in case of two or more numbers have common factors) = 40

GCF(400,251,840) x common factors =1 x 40 = 40

LCM(400,251,840) = ( 400 × 251 × 840 ) / 40

LCM(400,251,840) = 84336000 / 40

LCM(400,251,840) = 2108400


Lets's calculate GCF of 58,40,87

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2108400/1

Therefore the LCM of Fractions 400/58,251/40,840/87 is 2108400
