Greatest Common Factor
We found the factors 795,765 . The biggest common factor number is the GCF number.
So the greatest common factor 795,765 is 15.
Lets's calculate LCM of 921,697
Given numbers has no common factors except 1. So, there LCM is their product i.e 641937
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/641937
Therefore, the GCF of Fractions 795/921,765/697 is 15/641937
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 921,697 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,697) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(921,697) x common factors =1 x 1 = 1
LCM(921,697) = ( 921 × 697 ) / 1
LCM(921,697) = 641937 / 1
LCM(921,697) = 641937
