Greatest Common Factor

We found the factors 19,42,36,28 . The biggest common factor number is the GCF number.
So the greatest common factor 19,42,36,28 is 1.

Lets's calculate LCM of 50,31,31,419

31 50, 31, 31, 419
50, 1, 1, 419

∴ So the LCM of the given numbers is 31 x 50 x 1 x 1 x 419 = 649450

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/649450

Therefore, the GCF of Fractions 19/50,42/31,36/31,28/419 is 1/649450

Least Common Multiple of 50,31,31,419 with GCF Formula

Least Common Multiple of 50,31,31,419 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 50,31,31,419 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(50,31,31,419) = 1

common factors(in case of two or more numbers have common factors) = 31

GCF(50,31,31,419) x common factors =1 x 31 = 31

LCM(50,31,31,419) = ( 50 × 31 × 31 × 419 ) / 31

LCM(50,31,31,419) = 20132950 / 31

LCM(50,31,31,419) = 649450
