So the greatest common factor 780,121,244 is 1.

Lets's calculate LCM of 63,81,504

3 63, 81, 504
3 21, 27, 168
7 7, 9, 56
1, 9, 8

∴ So the LCM of the given numbers is 3 x 3 x 7 x 1 x 9 x 8 = 4536

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4536

Therefore, the GCF of Fractions 780/63,121/81,244/504 is 1/4536

Least Common Multiple of 63,81,504 with GCF Formula

Least Common Multiple of 63,81,504 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 63,81,504 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,81,504) = 9

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

GCF(63,81,504) x common factors =9 x 63 = 567

LCM(63,81,504) = ( 63 × 81 × 504 ) / 567

LCM(63,81,504) = 2571912 / 567

LCM(63,81,504) = 4536
