Lets's calculate LCM of 21,17,293

Given numbers has no common factors except 1. So, there LCM is their product i.e 104601

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/104601

Therefore, the GCF of Fractions 720/21,657/17,159/293 is 3/104601

Least Common Multiple of 21,17,293 with GCF Formula

Least Common Multiple of 21,17,293 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 21,17,293 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,17,293) = 1

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

GCF(21,17,293) x common factors =1 x 1 = 1

LCM(21,17,293) = ( 21 × 17 × 293 ) / 1

LCM(21,17,293) = 104601 / 1

LCM(21,17,293) = 104601
