Lets's calculate LCM of 858,289
Given numbers has no common factors except 1. So, there LCM is their product i.e 247962
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/247962
Therefore, the GCF of Fractions 580/858,7315/289 is 5/247962
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 858,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(858,289) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(858,289) x common factors =1 x 1 = 1
LCM(858,289) = ( 858 × 289 ) / 1
LCM(858,289) = 247962 / 1
LCM(858,289) = 247962
