Greatest Common Factor
We found the factors 423,8515 . The biggest common factor number is the GCF number.
So the greatest common factor 423,8515 is 1.
Lets's calculate LCM of 681,697
Given numbers has no common factors except 1. So, there LCM is their product i.e 474657
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/474657
Therefore, the GCF of Fractions 423/681,8515/697 is 1/474657
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 681,697 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(681,697) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(681,697) x common factors =1 x 1 = 1
LCM(681,697) = ( 681 × 697 ) / 1
LCM(681,697) = 474657 / 1
LCM(681,697) = 474657
