Lets's calculate GCF of 831,515
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 831
:1,3,277,831
Now, list down the factors of 515
:1,5,103,515
Greatest Common Factor
We found the factors 831,515 . The biggest common factor number is the GCF number.
So the greatest common factor 831,515 is 1.
Lets's calculate LCM of 508,223
Given numbers has no common factors except 1. So, there LCM is their product i.e 113284
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/113284
Therefore, the GCF of Fractions 831/508,515/223 is 1/113284
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 508,223 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(508,223) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(508,223) x common factors =1 x 1 = 1
LCM(508,223) = ( 508 × 223 ) / 1
LCM(508,223) = 113284 / 1
LCM(508,223) = 113284
