LCM of:

Least Common Multiple of 42/54,70/421,604/316

Given numbers are 42/54,70/421,604/316

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 42,70,604

Least Common Multiple of Numerators i.e. LCM of 42,70,604 is 63420.

GCF of Denominators means GCF of 54,421,316 as per the given fractions.

GCF of 54,421,316 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,70,604

LCM of Fractions 42/54,70/421,604/316 is 63420

2 42, 70, 604
7 21, 35, 302
3, 5, 302

∴ So the LCM of the given numbers is 2 x 7 x 3 x 5 x 302 = 63420

Least Common Multiple of 42,70,604 with GCF Formula

Least Common Multiple of 42,70,604 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 42,70,604 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,70,604) = 2

common factors(in case of two or more numbers have common factors) = 14

GCF(42,70,604) x common factors =2 x 14 = 28

LCM(42,70,604) = ( 42 × 70 × 604 ) / 28

LCM(42,70,604) = 1775760 / 28

LCM(42,70,604) = 63420


Lets's calculate GCF of 54,421,316

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 63420/1

Therefore the LCM of Fractions 42/54,70/421,604/316 is 63420
