Greatest Common Factor
We found the factors 640,337 . The biggest common factor number is the GCF number.
So the greatest common factor 640,337 is 1.
Lets's calculate LCM of 397,345
Given numbers has no common factors except 1. So, there LCM is their product i.e 136965
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/136965
Therefore, the GCF of Fractions 640/397,337/345 is 1/136965
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 397,345 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(397,345) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(397,345) x common factors =1 x 1 = 1
LCM(397,345) = ( 397 × 345 ) / 1
LCM(397,345) = 136965 / 1
LCM(397,345) = 136965
