Greatest Common Factor
We found the factors 897,721 . The biggest common factor number is the GCF number.
So the greatest common factor 897,721 is 1.
Lets's calculate LCM of 878,715
Given numbers has no common factors except 1. So, there LCM is their product i.e 627770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/627770
Therefore, the GCF of Fractions 897/878,721/715 is 1/627770
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 878,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(878,715) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(878,715) x common factors =1 x 1 = 1
LCM(878,715) = ( 878 × 715 ) / 1
LCM(878,715) = 627770 / 1
LCM(878,715) = 627770
