:1,2,3,4,6,12,19,38,57,76,114,228
Now, list down the factors of 285
:1,3,5,15,19,57,95,285
Greatest Common Factor
We found the factors 228,285 . The biggest common factor number is the GCF number.
So the greatest common factor 228,285 is 57.
Lets's calculate LCM of 128,401
Given numbers has no common factors except 1. So, there LCM is their product i.e 51328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 57/51328
Therefore, the GCF of Fractions 228/128,285/401 is 57/51328
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 128,401 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,401) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(128,401) x common factors =1 x 1 = 1
LCM(128,401) = ( 128 × 401 ) / 1
LCM(128,401) = 51328 / 1
LCM(128,401) = 51328
