Now, list down the factors of 221
:1,13,17,221
Now, list down the factors of 745
:1,5,149,745
Greatest Common Factor
We found the factors 221,745 . The biggest common factor number is the GCF number.
So the greatest common factor 221,745 is 1.
Lets's calculate LCM of 617,161
Given numbers has no common factors except 1. So, there LCM is their product i.e 99337
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/99337
Therefore, the GCF of Fractions 221/617,745/161 is 1/99337
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 617,161 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(617,161) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(617,161) x common factors =1 x 1 = 1
LCM(617,161) = ( 617 × 161 ) / 1
LCM(617,161) = 99337 / 1
LCM(617,161) = 99337
