Greatest Common Factor

We found the factors 33,28,34,47 . The biggest common factor number is the GCF number.
So the greatest common factor 33,28,34,47 is 1.

Lets's calculate LCM of 63,21,60,129

3 63, 21, 60, 129
7 21, 7, 20, 43
3, 1, 20, 43

∴ So the LCM of the given numbers is 3 x 7 x 3 x 1 x 20 x 43 = 54180

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54180

Therefore, the GCF of Fractions 33/63,28/21,34/60,47/129 is 1/54180

Least Common Multiple of 63,21,60,129 with GCF Formula

Least Common Multiple of 63,21,60,129 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 63,21,60,129 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,21,60,129) = 3

common factors(in case of two or more numbers have common factors) = 63

GCF(63,21,60,129) x common factors =3 x 63 = 189

LCM(63,21,60,129) = ( 63 × 21 × 60 × 129 ) / 189

LCM(63,21,60,129) = 10240020 / 189

LCM(63,21,60,129) = 54180
