Lets's calculate LCM of 748,589
Given numbers has no common factors except 1. So, there LCM is their product i.e 440572
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/440572
Therefore, the GCF of Fractions 390/748,7385/589 is 5/440572
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 748,589 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(748,589) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(748,589) x common factors =1 x 1 = 1
LCM(748,589) = ( 748 × 589 ) / 1
LCM(748,589) = 440572 / 1
LCM(748,589) = 440572
Here are some samples of GCF of Fractions calculations.
