Greatest Common Factor

We found the factors 24,79,55 . The biggest common factor number is the GCF number.
So the greatest common factor 24,79,55 is 1.

Lets's calculate LCM of 19,87,57

3 19, 87, 57
19 19, 29, 19
1, 29, 1

∴ So the LCM of the given numbers is 3 x 19 x 1 x 29 x 1 = 1653

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1653

Therefore, the GCF of Fractions 24/19,79/87,55/57 is 1/1653

Least Common Multiple of 19,87,57 with GCF Formula

Least Common Multiple of 19,87,57 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 19,87,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(19,87,57) = 1

common factors(in case of two or more numbers have common factors) = 57

GCF(19,87,57) x common factors =1 x 57 = 57

LCM(19,87,57) = ( 19 × 87 × 57 ) / 57

LCM(19,87,57) = 94221 / 57

LCM(19,87,57) = 1653
