Now, list down the factors of 786
:1,2,3,6,131,262,393,786
Now, list down the factors of 221
:1,13,17,221
Greatest Common Factor
We found the factors 786,221 . The biggest common factor number is the GCF number.
So the greatest common factor 786,221 is 1.
Lets's calculate LCM of 206,805
Given numbers has no common factors except 1. So, there LCM is their product i.e 165830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/165830
Therefore, the GCF of Fractions 786/206,221/805 is 1/165830
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 206,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(206,805) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(206,805) x common factors =1 x 1 = 1
LCM(206,805) = ( 206 × 805 ) / 1
LCM(206,805) = 165830 / 1
LCM(206,805) = 165830
