Least Common Multiple of 90/285,4242/9421

Given numbers are 90/285,4242/9421

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 90,4242

Least Common Multiple of Numerators i.e. LCM of 90,4242 is 63630.

GCF of Denominators means GCF of 285,9421 as per the given fractions.

GCF of 285,9421 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 90,4242

LCM of Fractions 90/285,4242/9421 is 63630

2 90, 4242
3 45, 2121
15, 707

∴ So the LCM of the given numbers is 2 x 3 x 15 x 707 = 63630

Least Common Multiple of 90,4242 with GCF Formula

Least Common Multiple of 90,4242 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 90,4242 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,4242) = 6

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

GCF(90,4242) x common factors =6 x 1 = 6

LCM(90,4242) = ( 90 × 4242 ) / 6

LCM(90,4242) = 381780 / 6

LCM(90,4242) = 63630


Lets's calculate GCF of 285,9421

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 63630/1

Therefore the LCM of Fractions 90/285,4242/9421 is 63630
