We found the factors 31,11,36,90 . The biggest common factor number is the GCF number.
So the greatest common factor 31,11,36,90 is 1.

Lets's calculate LCM of 38,13,74,329

2 38, 13, 74, 329
19, 13, 37, 329

∴ So the LCM of the given numbers is 2 x 19 x 13 x 37 x 329 = 6013462

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6013462

Therefore, the GCF of Fractions 31/38,11/13,36/74,90/329 is 1/6013462

Least Common Multiple of 38,13,74,329 with GCF Formula

Least Common Multiple of 38,13,74,329 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 38,13,74,329 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(38,13,74,329) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(38,13,74,329) x common factors =1 x 2 = 2

LCM(38,13,74,329) = ( 38 × 13 × 74 × 329 ) / 2

LCM(38,13,74,329) = 12026924 / 2

LCM(38,13,74,329) = 6013462
