Greatest Common Factor

We found the factors 93,81,51,48 . The biggest common factor number is the GCF number.
So the greatest common factor 93,81,51,48 is 3.

Lets's calculate LCM of 23,19,12,39

3 23, 19, 12, 39
23, 19, 4, 13

∴ So the LCM of the given numbers is 3 x 23 x 19 x 4 x 13 = 68172

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/68172

Therefore, the GCF of Fractions 93/23,81/19,51/12,48/39 is 3/68172

Least Common Multiple of 23,19,12,39 with GCF Formula

Least Common Multiple of 23,19,12,39 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 23,19,12,39 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,19,12,39) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(23,19,12,39) x common factors =1 x 3 = 3

LCM(23,19,12,39) = ( 23 × 19 × 12 × 39 ) / 3

LCM(23,19,12,39) = 204516 / 3

LCM(23,19,12,39) = 68172
