:1,3,5,11,15,25,33,55,75,165,275,825
Now, list down the factors of 981
:1,3,9,109,327,981
Greatest Common Factor
We found the factors 825,981 . The biggest common factor number is the GCF number.
So the greatest common factor 825,981 is 3.
Lets's calculate LCM of 817,213
Given numbers has no common factors except 1. So, there LCM is their product i.e 174021
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/174021
Therefore, the GCF of Fractions 825/817,981/213 is 3/174021
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 817,213 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(817,213) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(817,213) x common factors =1 x 1 = 1
LCM(817,213) = ( 817 × 213 ) / 1
LCM(817,213) = 174021 / 1
LCM(817,213) = 174021
