LCM of:

Least Common Multiple of 13/711,20/921,490/127

Given numbers are 13/711,20/921,490/127

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 13,20,490

Least Common Multiple of Numerators i.e. LCM of 13,20,490 is 12740.

GCF of Denominators means GCF of 711,921,127 as per the given fractions.

GCF of 711,921,127 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,20,490

LCM of Fractions 13/711,20/921,490/127 is 12740

2 13, 20, 490
5 13, 10, 245
13, 2, 49

∴ So the LCM of the given numbers is 2 x 5 x 13 x 2 x 49 = 12740

Least Common Multiple of 13,20,490 with GCF Formula

Least Common Multiple of 13,20,490 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 13,20,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,20,490) = 1

common factors(in case of two or more numbers have common factors) = 10

GCF(13,20,490) x common factors =1 x 10 = 10

LCM(13,20,490) = ( 13 × 20 × 490 ) / 10

LCM(13,20,490) = 127400 / 10

LCM(13,20,490) = 12740


Lets's calculate GCF of 711,921,127

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12740/1

Therefore the LCM of Fractions 13/711,20/921,490/127 is 12740
