∴ So the GCF of the given numbers is 103 = 103
Now, list down the factors of 721
:1,7,103,721
Now, list down the factors of 103
:1,103
Greatest Common Factor
We found the factors 721,103 . The biggest common factor number is the GCF number.
So the greatest common factor 721,103 is 103.
Lets's calculate LCM of 256,839
Given numbers has no common factors except 1. So, there LCM is their product i.e 214784
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 103/214784
Therefore, the GCF of Fractions 721/256,103/839 is 103/214784
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 256,839 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(256,839) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(256,839) x common factors =1 x 1 = 1
LCM(256,839) = ( 256 × 839 ) / 1
LCM(256,839) = 214784 / 1
LCM(256,839) = 214784
