Greatest Common Factor

We found the factors 34,55,21,39 . The biggest common factor number is the GCF number.
So the greatest common factor 34,55,21,39 is 1.

Lets's calculate LCM of 13,65,91,867

13 13, 65, 91, 867
1, 5, 7, 867

∴ So the LCM of the given numbers is 13 x 1 x 5 x 7 x 867 = 394485

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/394485

Therefore, the GCF of Fractions 34/13,55/65,21/91,39/867 is 1/394485

Least Common Multiple of 13,65,91,867 with GCF Formula

Least Common Multiple of 13,65,91,867 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 13,65,91,867 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,65,91,867) = 1

common factors(in case of two or more numbers have common factors) = 169

GCF(13,65,91,867) x common factors =1 x 169 = 169

LCM(13,65,91,867) = ( 13 × 65 × 91 × 867 ) / 169

LCM(13,65,91,867) = 66667965 / 169

LCM(13,65,91,867) = 394485
