So the greatest common factor 54,15,99,51 is 3.

Lets's calculate LCM of 18,18,96,663

2 18, 18, 96, 663
3 9, 9, 48, 663
3 3, 3, 16, 221
1, 1, 16, 221

∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 1 x 16 x 221 = 63648

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/63648

Therefore, the GCF of Fractions 54/18,15/18,99/96,51/663 is 3/63648

Least Common Multiple of 18,18,96,663 with GCF Formula

Least Common Multiple of 18,18,96,663 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 18,18,96,663 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,18,96,663) = 3

common factors(in case of two or more numbers have common factors) = 108

GCF(18,18,96,663) x common factors =3 x 108 = 324

LCM(18,18,96,663) = ( 18 × 18 × 96 × 663 ) / 324

LCM(18,18,96,663) = 20621952 / 324

LCM(18,18,96,663) = 63648
