Given numbers are 21/641,969/345,410/642

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 21,969,410

Least Common Multiple of Numerators i.e. LCM of 21,969,410 is 2781030.

GCF of Denominators means GCF of 641,345,642 as per the given fractions.

GCF of 641,345,642 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,969,410

LCM of Fractions 21/641,969/345,410/642 is 2781030

3 21, 969, 410
7, 323, 410

∴ So the LCM of the given numbers is 3 x 7 x 323 x 410 = 2781030

Least Common Multiple of 21,969,410 with GCF Formula

Least Common Multiple of 21,969,410 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 21,969,410 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,969,410) = 1

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

GCF(21,969,410) x common factors =1 x 3 = 3

LCM(21,969,410) = ( 21 × 969 × 410 ) / 3

LCM(21,969,410) = 8343090 / 3

LCM(21,969,410) = 2781030


Lets's calculate GCF of 641,345,642

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2781030/1

Therefore the LCM of Fractions 21/641,969/345,410/642 is 2781030
