Lets's calculate LCM of 669,1910
Given numbers has no common factors except 1. So, there LCM is their product i.e 1277790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1277790
Therefore, the GCF of Fractions 1745/669,1715/1910 is 5/1277790
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 669,1910 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(669,1910) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(669,1910) x common factors =1 x 1 = 1
LCM(669,1910) = ( 669 × 1910 ) / 1
LCM(669,1910) = 1277790 / 1
LCM(669,1910) = 1277790
