List of positive integer factors of 789 that divides 789 without a remainder.
1,3,263,789
Greatest Common Factor
We found the factors 798,789 . The biggest common factor number is the GCF number.
So the greatest common factor 798,789 is 3.
Lets's calculate LCM of 931,697
Given numbers has no common factors except 1. So, there LCM is their product i.e 648907
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/648907
Therefore, the GCF of Fractions 798/931,789/697 is 3/648907
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 931,697 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,697) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(931,697) x common factors =1 x 1 = 1
LCM(931,697) = ( 931 × 697 ) / 1
LCM(931,697) = 648907 / 1
LCM(931,697) = 648907
