Lets's calculate LCM of 17,465

Given numbers has no common factors except 1. So, there LCM is their product i.e 7905

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7905

Therefore, the GCF of Fractions 349/17,390/465 is 1/7905

Least Common Multiple of 17,465 with GCF Formula

Least Common Multiple of 17,465 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 17,465 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(17,465) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(17,465) x common factors =1 x 1 = 1

LCM(17,465) = ( 17 × 465 ) / 1

LCM(17,465) = 7905 / 1

LCM(17,465) = 7905
