:1,929
Greatest Common Factor
We found the factors 431,929 . The biggest common factor number is the GCF number.
So the greatest common factor 431,929 is 1.
Lets's calculate LCM of 317,639
Given numbers has no common factors except 1. So, there LCM is their product i.e 202563
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/202563
Therefore, the GCF of Fractions 431/317,929/639 is 1/202563
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 317,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(317,639) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(317,639) x common factors =1 x 1 = 1
LCM(317,639) = ( 317 × 639 ) / 1
LCM(317,639) = 202563 / 1
LCM(317,639) = 202563
