Greatest Common Factor
We found the factors 660,745 . The biggest common factor number is the GCF number.
So the greatest common factor 660,745 is 5.
Lets's calculate LCM of 517,736
Given numbers has no common factors except 1. So, there LCM is their product i.e 380512
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/380512
Therefore, the GCF of Fractions 660/517,745/736 is 5/380512
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 517,736 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(517,736) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(517,736) x common factors =1 x 1 = 1
LCM(517,736) = ( 517 × 736 ) / 1
LCM(517,736) = 380512 / 1
LCM(517,736) = 380512
