Least Common Multiple of 53/90,39/40,61/90,21/264

Given numbers are 53/90,39/40,61/90,21/264

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 53,39,61,21

Least Common Multiple of Numerators i.e. LCM of 53,39,61,21 is 882609.

GCF of Denominators means GCF of 90,40,90,264 as per the given fractions.

GCF of 90,40,90,264 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 53,39,61,21

LCM of Fractions 53/90,39/40,61/90,21/264 is 882609/2

3 53, 39, 61, 21
53, 13, 61, 7

∴ So the LCM of the given numbers is 3 x 53 x 13 x 61 x 7 = 882609

Least Common Multiple of 53,39,61,21 with GCF Formula

Least Common Multiple of 53,39,61,21 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 53,39,61,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(53,39,61,21) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(53,39,61,21) x common factors =1 x 3 = 3

LCM(53,39,61,21) = ( 53 × 39 × 61 × 21 ) / 3

LCM(53,39,61,21) = 2647827 / 3

LCM(53,39,61,21) = 882609


Lets's calculate GCF of 90,40,90,264

2 90, 40, 90, 264
45, 20, 45, 132

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 882609/2

Therefore the LCM of Fractions 53/90,39/40,61/90,21/264 is 882609/2
