Lets's calculate LCM of 54,17,287
Given numbers has no common factors except 1. So, there LCM is their product i.e 263466
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/263466
Therefore, the GCF of Fractions 76/54,82/17,821/287 is 1/263466
Least Common Multiple of 54,17,287 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 54,17,287 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(54,17,287) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(54,17,287) x common factors =1 x 1 = 1
LCM(54,17,287) = ( 54 × 17 × 287 ) / 1
LCM(54,17,287) = 263466 / 1
LCM(54,17,287) = 263466
