Greatest Common Factor
We found the factors 8421,7398 . The biggest common factor number is the GCF number.
So the greatest common factor 8421,7398 is 3.
Lets's calculate LCM of 103,202
Given numbers has no common factors except 1. So, there LCM is their product i.e 20806
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/20806
Therefore, the GCF of Fractions 8421/103,7398/202 is 3/20806
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 103,202 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(103,202) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(103,202) x common factors =1 x 1 = 1
LCM(103,202) = ( 103 × 202 ) / 1
LCM(103,202) = 20806 / 1
LCM(103,202) = 20806
