So the greatest common factor 13,23,45 is 1.

Lets's calculate LCM of 66,60,384

2 66, 60, 384
2 33, 30, 192
3 33, 15, 96
11, 5, 32

∴ So the LCM of the given numbers is 2 x 2 x 3 x 11 x 5 x 32 = 21120

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21120

Therefore, the GCF of Fractions 13/66,23/60,45/384 is 1/21120

Least Common Multiple of 66,60,384 with GCF Formula

Least Common Multiple of 66,60,384 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 66,60,384 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,60,384) = 6

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

GCF(66,60,384) x common factors =6 x 12 = 72

LCM(66,60,384) = ( 66 × 60 × 384 ) / 72

LCM(66,60,384) = 1520640 / 72

LCM(66,60,384) = 21120
