Therefore, the GCF of 231/257,911/109 is 1/28013.
To find the highest common factor of 231,911, we have to find the factors of both numbers and list the highest common factor.
The factors of 231 are 1, 3, 7, 11, 21, 33, 77, 231
The factors of 911 are 1, 911
The HCF of 231,911 is 1.
Lets's calculate GCF of 231,911
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 231
:1,3,7,11,21,33,77,231
Now, list down the factors of 911
:1,911
Greatest Common Factor
We found the factors 231,911 . The biggest common factor number is the GCF number.
So the greatest common factor 231,911 is 1.
Lets's calculate LCM of 257,109
Given numbers has no common factors except 1. So, there LCM is their product i.e 28013
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28013
Therefore, the GCF of Fractions 231/257,911/109 is 1/28013
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 257,109 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,109) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,109) x common factors =1 x 1 = 1
LCM(257,109) = ( 257 × 109 ) / 1
LCM(257,109) = 28013 / 1
LCM(257,109) = 28013
