1,3,17,51,73,219,1241,3723
Greatest Common Factor
We found the factors 249,3723 . The biggest common factor number is the GCF number.
So the greatest common factor 249,3723 is 3.
Lets's calculate LCM of 485,972
Given numbers has no common factors except 1. So, there LCM is their product i.e 471420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/471420
Therefore, the GCF of Fractions 249/485,3723/972 is 3/471420
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 485,972 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(485,972) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(485,972) x common factors =1 x 1 = 1
LCM(485,972) = ( 485 × 972 ) / 1
LCM(485,972) = 471420 / 1
LCM(485,972) = 471420
Here are some samples of GCF of Fractions calculations.
