LCM of:

Least Common Multiple of 42/645,9006/6423

Given numbers are 42/645,9006/6423

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 42,9006

Least Common Multiple of Numerators i.e. LCM of 42,9006 is 63042.

GCF of Denominators means GCF of 645,6423 as per the given fractions.

GCF of 645,6423 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,9006

LCM of Fractions 42/645,9006/6423 is 21014

2 42, 9006
3 21, 4503
7, 1501

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1501 = 63042

Least Common Multiple of 42,9006 with GCF Formula

Least Common Multiple of 42,9006 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 42,9006 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,9006) = 6

common factors(in case of two or more numbers have common factors) = 1

GCF(42,9006) x common factors =6 x 1 = 6

LCM(42,9006) = ( 42 × 9006 ) / 6

LCM(42,9006) = 378252 / 6

LCM(42,9006) = 63042


Lets's calculate GCF of 645,6423

3 645, 6423
215, 2141

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 63042/3

Therefore the LCM of Fractions 42/645,9006/6423 is 21014
