Greatest Common Factor
We found the factors 627,421 . The biggest common factor number is the GCF number.
So the greatest common factor 627,421 is 1.
Lets's calculate LCM of 291,997
Given numbers has no common factors except 1. So, there LCM is their product i.e 290127
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/290127
Therefore, the GCF of Fractions 627/291,421/997 is 1/290127
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 291,997 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(291,997) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(291,997) x common factors =1 x 1 = 1
LCM(291,997) = ( 291 × 997 ) / 1
LCM(291,997) = 290127 / 1
LCM(291,997) = 290127
