Lets's calculate LCM of 23,40,169

Given numbers has no common factors except 1. So, there LCM is their product i.e 155480

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/155480

Therefore, the GCF of Fractions 819/23,354/40,162/169 is 3/155480

Least Common Multiple of 23,40,169 with GCF Formula

Least Common Multiple of 23,40,169 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 23,40,169 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,40,169) = 1

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

GCF(23,40,169) x common factors =1 x 1 = 1

LCM(23,40,169) = ( 23 × 40 × 169 ) / 1

LCM(23,40,169) = 155480 / 1

LCM(23,40,169) = 155480
