Greatest Common Factor

We found the factors 55,84,68,51 . The biggest common factor number is the GCF number.
So the greatest common factor 55,84,68,51 is 1.

Lets's calculate LCM of 75,25,13,915

3 75, 25, 13, 915
5 25, 25, 13, 305
5 5, 5, 13, 61
1, 1, 13, 61

∴ So the LCM of the given numbers is 3 x 5 x 5 x 1 x 1 x 13 x 61 = 59475

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/59475

Least Common Multiple of 75,25,13,915 with GCF Formula

Least Common Multiple of 75,25,13,915 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 75,25,13,915 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(75,25,13,915) = 1

common factors(in case of two or more numbers have common factors) = 375

GCF(75,25,13,915) x common factors =1 x 375 = 375

LCM(75,25,13,915) = ( 75 × 25 × 13 × 915 ) / 375

LCM(75,25,13,915) = 22303125 / 375

LCM(75,25,13,915) = 59475
