Greatest Common Factor of 63/198,84/771

Given fractions are 63/198,84/771

Formula to find GCF of Fractions is

GCF = GCF of Numerators/LCM of Denominators

As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators

In the given fractions GCF of Numerators means GCF of 63,84

Greatest Common Factor of Numerators i.e. GCF of 63,84 is 21 .

LCM of Denominators means LCM of 198,771 as per the given fractions.

LCM of 198,771 is 50886 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 63,84

GCF of Fractions 63/198,84/771 is 21/50886

3 63, 84
7 21, 28
3, 4

∴ So the GCF of the given numbers is 3 x 7 = 21

Least Common Multiple of 198,771 with GCF Formula

Least Common Multiple of 198,771 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 198,771 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(198,771) = 3

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

GCF(198,771) x common factors =3 x 1 = 3

LCM(198,771) = ( 198 × 771 ) / 3

LCM(198,771) = 152658 / 3

LCM(198,771) = 50886
