:1,2,3,6,9,18,27,54,81,162,243,486
Now, list down the factors of 221
:1,13,17,221
Greatest Common Factor
We found the factors 486,221 . The biggest common factor number is the GCF number.
So the greatest common factor 486,221 is 1.
Lets's calculate LCM of 258,665
Given numbers has no common factors except 1. So, there LCM is their product i.e 171570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/171570
Therefore, the GCF of Fractions 486/258,221/665 is 1/171570
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 258,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(258,665) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(258,665) x common factors =1 x 1 = 1
LCM(258,665) = ( 258 × 665 ) / 1
LCM(258,665) = 171570 / 1
LCM(258,665) = 171570
