:1,17,289
Now, list down the factors of 872
:1,2,4,8,109,218,436,872
Greatest Common Factor
We found the factors 289,872 . The biggest common factor number is the GCF number.
So the greatest common factor 289,872 is 1.
Lets's calculate LCM of 81,338
Given numbers has no common factors except 1. So, there LCM is their product i.e 27378
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/27378
Therefore, the GCF of Fractions 289/81,872/338 is 1/27378
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 81,338 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,338) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,338) x common factors =1 x 1 = 1
LCM(81,338) = ( 81 × 338 ) / 1
LCM(81,338) = 27378 / 1
LCM(81,338) = 27378
