Greatest Common Factor
We found the factors 456,362,812 . The biggest common factor number is the GCF number.
So the greatest common factor 456,362,812 is 2.
Lets's calculate LCM of 20,31,917
Given numbers has no common factors except 1. So, there LCM is their product i.e 568540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/568540
Therefore, the GCF of Fractions 456/20,362/31,812/917 is 2/568540
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 20,31,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,31,917) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(20,31,917) x common factors =1 x 1 = 1
LCM(20,31,917) = ( 20 × 31 × 917 ) / 1
LCM(20,31,917) = 568540 / 1
LCM(20,31,917) = 568540
