Lets's calculate LCM of 694,679
Given numbers has no common factors except 1. So, there LCM is their product i.e 471226
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/471226
Therefore, the GCF of Fractions 450/694,396/679 is 18/471226
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 694,679 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(694,679) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(694,679) x common factors =1 x 1 = 1
LCM(694,679) = ( 694 × 679 ) / 1
LCM(694,679) = 471226 / 1
LCM(694,679) = 471226
