Lets's calculate LCM of 399,289
Given numbers has no common factors except 1. So, there LCM is their product i.e 115311
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/115311
Therefore, the GCF of Fractions 644/399,4492/289 is 4/115311
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 399,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(399,289) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(399,289) x common factors =1 x 1 = 1
LCM(399,289) = ( 399 × 289 ) / 1
LCM(399,289) = 115311 / 1
LCM(399,289) = 115311
Here are some samples of GCF of Fractions calculations.
