Greatest Common Factor
We found the factors 672,648 . The biggest common factor number is the GCF number.
So the greatest common factor 672,648 is 24.
Lets's calculate LCM of 118,309
Given numbers has no common factors except 1. So, there LCM is their product i.e 36462
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 24/36462
Therefore, the GCF of Fractions 672/118,648/309 is 24/36462
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 118,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(118,309) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(118,309) x common factors =1 x 1 = 1
LCM(118,309) = ( 118 × 309 ) / 1
LCM(118,309) = 36462 / 1
LCM(118,309) = 36462
