Greatest Common Factor
We found the factors 885,2490 . The biggest common factor number is the GCF number.
So the greatest common factor 885,2490 is 15.
Lets's calculate LCM of 238,841
Given numbers has no common factors except 1. So, there LCM is their product i.e 200158
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/200158
Therefore, the GCF of Fractions 885/238,2490/841 is 15/200158
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 238,841 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(238,841) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(238,841) x common factors =1 x 1 = 1
LCM(238,841) = ( 238 × 841 ) / 1
LCM(238,841) = 200158 / 1
LCM(238,841) = 200158
Here are some samples of GCF of Fractions calculations.
