Lets's calculate LCM of 413,745
Given numbers has no common factors except 1. So, there LCM is their product i.e 307685
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/307685
Therefore, the GCF of Fractions 18/413,51/745 is 3/307685
Least Common Multiple of 413,745 with GCF Formula
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 413,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(413,745) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(413,745) x common factors =1 x 1 = 1
LCM(413,745) = ( 413 × 745 ) / 1
LCM(413,745) = 307685 / 1
LCM(413,745) = 307685
