Greatest Common Factor

We found the factors 13,84,57,923 . The biggest common factor number is the GCF number.
So the greatest common factor 13,84,57,923 is 1.

Lets's calculate LCM of 33,19,42,65

3 33, 19, 42, 65
11, 19, 14, 65

∴ So the LCM of the given numbers is 3 x 11 x 19 x 14 x 65 = 570570

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/570570

Therefore, the GCF of Fractions 13/33,84/19,57/42,923/65 is 1/570570

Least Common Multiple of 33,19,42,65 with GCF Formula

Least Common Multiple of 33,19,42,65 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 33,19,42,65 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(33,19,42,65) = 1

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

GCF(33,19,42,65) x common factors =1 x 3 = 3

LCM(33,19,42,65) = ( 33 × 19 × 42 × 65 ) / 3

LCM(33,19,42,65) = 1711710 / 3

LCM(33,19,42,65) = 570570
