:1,2,4,8,16,29,58,116,232,464
Greatest Common Factor
We found the factors 256,464 . The biggest common factor number is the GCF number.
So the greatest common factor 256,464 is 16.
Lets's calculate LCM of 497,663
Given numbers has no common factors except 1. So, there LCM is their product i.e 329511
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/329511
Therefore, the GCF of Fractions 256/497,464/663 is 16/329511
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 497,663 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(497,663) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(497,663) x common factors =1 x 1 = 1
LCM(497,663) = ( 497 × 663 ) / 1
LCM(497,663) = 329511 / 1
LCM(497,663) = 329511
