We found the factors 621,4785 . The biggest common factor number is the GCF number.
So the greatest common factor 621,4785 is 3.
Lets's calculate LCM of 439,367
Given numbers has no common factors except 1. So, there LCM is their product i.e 161113
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/161113
Therefore, the GCF of Fractions 621/439,4785/367 is 3/161113
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 439,367 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(439,367) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(439,367) x common factors =1 x 1 = 1
LCM(439,367) = ( 439 × 367 ) / 1
LCM(439,367) = 161113 / 1
LCM(439,367) = 161113
Here are some samples of GCF of Fractions calculations.
