Least Common Multiple of 42/43,812/37,669/139

Given numbers are 42/43,812/37,669/139

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 42,812,669

Least Common Multiple of Numerators i.e. LCM of 42,812,669 is 543228.

GCF of Denominators means GCF of 43,37,139 as per the given fractions.

GCF of 43,37,139 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,812,669

LCM of Fractions 42/43,812/37,669/139 is 543228

2 42, 812, 669
3 21, 406, 669
7 7, 406, 223
1, 58, 223

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 58 x 223 = 543228

Least Common Multiple of 42,812,669 with GCF Formula

Least Common Multiple of 42,812,669 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 42,812,669 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,812,669) = 1

common factors(in case of two or more numbers have common factors) = 42

GCF(42,812,669) x common factors =1 x 42 = 42

LCM(42,812,669) = ( 42 × 812 × 669 ) / 42

LCM(42,812,669) = 22815576 / 42

LCM(42,812,669) = 543228


Lets's calculate GCF of 43,37,139

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 543228/1

Therefore the LCM of Fractions 42/43,812/37,669/139 is 543228
