Lets's calculate LCM of 15,99,288

3 15, 99, 288
3 5, 33, 96
5, 11, 32

∴ So the LCM of the given numbers is 3 x 3 x 5 x 11 x 32 = 15840

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15840

Therefore, the GCF of Fractions 14/15,39/99,81/288 is 1/15840

Least Common Multiple of 15,99,288 with GCF Formula

Least Common Multiple of 15,99,288 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 15,99,288 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,99,288) = 3

common factors(in case of two or more numbers have common factors) = 9

GCF(15,99,288) x common factors =3 x 9 = 27

LCM(15,99,288) = ( 15 × 99 × 288 ) / 27

LCM(15,99,288) = 427680 / 27

LCM(15,99,288) = 15840
