Lets's calculate GCF of 305,681
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 305
:1,5,61,305
Now, list down the factors of 681
:1,3,227,681
Greatest Common Factor
We found the factors 305,681 . The biggest common factor number is the GCF number.
So the greatest common factor 305,681 is 1.
Lets's calculate LCM of 472,547
Given numbers has no common factors except 1. So, there LCM is their product i.e 258184
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/258184
Therefore, the GCF of Fractions 305/472,681/547 is 1/258184
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 472,547 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,547) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(472,547) x common factors =1 x 1 = 1
LCM(472,547) = ( 472 × 547 ) / 1
LCM(472,547) = 258184 / 1
LCM(472,547) = 258184
