Greatest Common Factor
We found the factors 88,92,388 . The biggest common factor number is the GCF number.
So the greatest common factor 88,92,388 is 4.
Lets's calculate LCM of 71,806,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 56710966
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/56710966
Therefore, the GCF of Fractions 88/71,92/806,388/991 is 4/56710966
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 71,806,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,806,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,806,991) x common factors =1 x 1 = 1
LCM(71,806,991) = ( 71 × 806 × 991 ) / 1
LCM(71,806,991) = 56710966 / 1
LCM(71,806,991) = 56710966
Here are some samples of GCF of Fractions calculations.
