Lets's calculate GCF of 721,309
103 | 721, 309 |
7, 3 |
∴ 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 309
:1,3,103,309
Greatest Common Factor
We found the factors 721,309 . The biggest common factor number is the GCF number.
So the greatest common factor 721,309 is 103.
Lets's calculate LCM of 568,979
Given numbers has no common factors except 1. So, there LCM is their product i.e 556072
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 103/556072
Therefore, the GCF of Fractions 721/568,309/979 is 103/556072
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 568,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(568,979) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(568,979) x common factors =1 x 1 = 1
LCM(568,979) = ( 568 × 979 ) / 1
LCM(568,979) = 556072 / 1
LCM(568,979) = 556072
