Greatest Common Factor
We found the factors 231,8100 . The biggest common factor number is the GCF number.
So the greatest common factor 231,8100 is 3.
Lets's calculate LCM of 239,982
Given numbers has no common factors except 1. So, there LCM is their product i.e 234698
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/234698
Therefore, the GCF of Fractions 231/239,8100/982 is 3/234698
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 239,982 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(239,982) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(239,982) x common factors =1 x 1 = 1
LCM(239,982) = ( 239 × 982 ) / 1
LCM(239,982) = 234698 / 1
LCM(239,982) = 234698
Here are some samples of GCF of Fractions calculations.
