Lets's calculate LCM of 24,12,165

2 24, 12, 165
2 12, 6, 165
3 3, 6, 165
1, 2, 55

∴ So the LCM of the given numbers is 2 x 2 x 3 x 1 x 2 x 55 = 1320

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1320

Therefore, the GCF of Fractions 27/24,21/12,613/165 is 1/1320

Least Common Multiple of 24,12,165 with GCF Formula

Least Common Multiple of 24,12,165 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 24,12,165 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(24,12,165) = 3

common factors(in case of two or more numbers have common factors) = 12

GCF(24,12,165) x common factors =3 x 12 = 36

LCM(24,12,165) = ( 24 × 12 × 165 ) / 36

LCM(24,12,165) = 47520 / 36

LCM(24,12,165) = 1320
