Lets's calculate GCF of 271,170
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 271
:1,271
Now, list down the factors of 170
:1,2,5,10,17,34,85,170
Greatest Common Factor
We found the factors 271,170 . The biggest common factor number is the GCF number.
So the greatest common factor 271,170 is 1.
Lets's calculate LCM of 57,391
Given numbers has no common factors except 1. So, there LCM is their product i.e 22287
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/22287
Therefore, the GCF of Fractions 271/57,170/391 is 1/22287
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 57,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,391) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(57,391) x common factors =1 x 1 = 1
LCM(57,391) = ( 57 × 391 ) / 1
LCM(57,391) = 22287 / 1
LCM(57,391) = 22287
