Greatest Common Factor
We found the factors 810,668 . The biggest common factor number is the GCF number.
So the greatest common factor 810,668 is 2.
Lets's calculate LCM of 988,563
Given numbers has no common factors except 1. So, there LCM is their product i.e 556244
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/556244
Therefore, the GCF of Fractions 810/988,668/563 is 2/556244
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 988,563 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(988,563) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(988,563) x common factors =1 x 1 = 1
LCM(988,563) = ( 988 × 563 ) / 1
LCM(988,563) = 556244 / 1
LCM(988,563) = 556244
