Now, list down the factors of 317
:1,317
Now, list down the factors of 220
:1,2,4,5,10,11,20,22,44,55,110,220
Greatest Common Factor
We found the factors 317,220 . The biggest common factor number is the GCF number.
So the greatest common factor 317,220 is 1.
Lets's calculate LCM of 865,768
Given numbers has no common factors except 1. So, there LCM is their product i.e 664320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/664320
Therefore, the GCF of Fractions 317/865,220/768 is 1/664320
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 865,768 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(865,768) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(865,768) x common factors =1 x 1 = 1
LCM(865,768) = ( 865 × 768 ) / 1
LCM(865,768) = 664320 / 1
LCM(865,768) = 664320
