Now, list down the factors of 915
:1,3,5,15,61,183,305,915
Now, list down the factors of 857
:1,857
Greatest Common Factor
We found the factors 915,857 . The biggest common factor number is the GCF number.
So the greatest common factor 915,857 is 1.
Lets's calculate LCM of 61,2605
Given numbers has no common factors except 1. So, there LCM is their product i.e 158905
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/158905
Therefore, the GCF of Fractions 915/61,857/2605 is 1/158905
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 61,2605 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,2605) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,2605) x common factors =1 x 1 = 1
LCM(61,2605) = ( 61 × 2605 ) / 1
LCM(61,2605) = 158905 / 1
LCM(61,2605) = 158905
