Greatest Common Factor
We found the factors 9990,8172 . The biggest common factor number is the GCF number.
So the greatest common factor 9990,8172 is 18.
Lets's calculate LCM of 83,851
Given numbers has no common factors except 1. So, there LCM is their product i.e 70633
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/70633
Therefore, the GCF of Fractions 9990/83,8172/851 is 18/70633
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 83,851 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,851) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,851) x common factors =1 x 1 = 1
LCM(83,851) = ( 83 × 851 ) / 1
LCM(83,851) = 70633 / 1
LCM(83,851) = 70633
