Lets's calculate LCM of 19,29,60

Given numbers has no common factors except 1. So, there LCM is their product i.e 33060

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33060

Therefore, the GCF of Fractions 121/19,400/29,399/60 is 1/33060

Least Common Multiple of 19,29,60 with GCF Formula

Least Common Multiple of 19,29,60 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 19,29,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(19,29,60) = 1

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

GCF(19,29,60) x common factors =1 x 1 = 1

LCM(19,29,60) = ( 19 × 29 × 60 ) / 1

LCM(19,29,60) = 33060 / 1

LCM(19,29,60) = 33060
