Answer:
The least possible sum for a+b+c is 18.
Step-by-step explanation:
As given a,b and c are positive integers and abc = 210
So, let us consider some situation in which the product abc = 20
- If a, b and c are 5, 6 and 7 then
abc = 210 & a+b+c = 18
- If a, b and c are 3, 7 and 10 then
abc = 210 & a+b+c = 20
- If a, b and c are 7, 15 and 2 then
abc = 24 & a+b+c = 24
- If a, b and c are 2, 5 and 21 then
abc = 210 & a+b+c = 28
From all of the above situation the least sum is 18 when a, b and c are 5, 6 and 7 respectively.
It's called the least squares method because the parameters of the regression line are adjusted in such a way that the sum of squares of the difference (between the actual and predicted values) is a minimum.
