Greatest Common Factor
We found the factors 73,47,36,82 . The biggest common factor number is the GCF number.
So the greatest common factor 73,47,36,82 is 1.
Lets's calculate LCM of 31,29,21,419
Given numbers has no common factors except 1. So, there LCM is their product i.e 7910301
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7910301
Therefore, the GCF of Fractions 73/31,47/29,36/21,82/419 is 1/7910301
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 31,29,21,419 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,29,21,419) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,29,21,419) x common factors =1 x 1 = 1
LCM(31,29,21,419) = ( 31 × 29 × 21 × 419 ) / 1
LCM(31,29,21,419) = 7910301 / 1
LCM(31,29,21,419) = 7910301
Here are some samples of GCF of Fractions calculations.
