:1,3,5,11,15,25,33,55,75,165,275,825
Now, list down the factors of 171
:1,3,9,19,57,171
Greatest Common Factor
We found the factors 825,171 . The biggest common factor number is the GCF number.
So the greatest common factor 825,171 is 3.
Lets's calculate LCM of 81,5395
Given numbers has no common factors except 1. So, there LCM is their product i.e 436995
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/436995
Therefore, the GCF of Fractions 825/81,171/5395 is 3/436995
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 81,5395 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,5395) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,5395) x common factors =1 x 1 = 1
LCM(81,5395) = ( 81 × 5395 ) / 1
LCM(81,5395) = 436995 / 1
LCM(81,5395) = 436995
