Greatest Common Factor
We found the factors 712,6643 . The biggest common factor number is the GCF number.
So the greatest common factor 712,6643 is 1.
Lets's calculate LCM of 689,1813
Given numbers has no common factors except 1. So, there LCM is their product i.e 1249157
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1249157
Therefore, the GCF of Fractions 712/689,6643/1813 is 1/1249157
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 689,1813 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,1813) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,1813) x common factors =1 x 1 = 1
LCM(689,1813) = ( 689 × 1813 ) / 1
LCM(689,1813) = 1249157 / 1
LCM(689,1813) = 1249157
