Greatest Common Factor
We found the factors 318,175 . The biggest common factor number is the GCF number.
So the greatest common factor 318,175 is 1.
Lets's calculate LCM of 998,721
Given numbers has no common factors except 1. So, there LCM is their product i.e 719558
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/719558
Therefore, the GCF of Fractions 318/998,175/721 is 1/719558
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 998,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(998,721) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(998,721) x common factors =1 x 1 = 1
LCM(998,721) = ( 998 × 721 ) / 1
LCM(998,721) = 719558 / 1
LCM(998,721) = 719558
