Here we must do two things. First we must find the smallest integer with 3 factors, then we must add those factors so that we can obtain our answer.

Looking at numbers less than 9 with only 3 factors, the only possibility is the number 4, whose factors are 1, 2, and 4.

The sum of these factors is 1 + 2 + 4 = 7

The factors of 64 are: 1,2,4,8,16,32,64. Therefore, 128 could be the product of 16 and 8.

Listing all the factors of 52: 1,2,4,13,26,52.

3 is not one of the factors.

1, 2, 3, 4, 6, 9, 12, 18, 36 are all of the factors of 36. 

The factors of a number are all the numbers that can be multiplied by an integer to get that number.

$\displaystyle GCF$:  the largest factor that divides evenly into all numbers

$\displaystyle LCM$:  the smallest non-zero number that divides evenly into all numbers.  If you are unable to find the GCF, then it is 1.

Prime factorize all numbers:

$\displaystyle 10 = 2\cdot 5$

$\displaystyle 12 = 2\cdot 2\cdot 3$

$\displaystyle 15 = 3\cdot 5$

$\displaystyle GCF$ $\displaystyle = 1$, because all numbers are relatively prime.

$\displaystyle LCM$ $\displaystyle =$  $\displaystyle 2\cdot 2\cdot 3\cdot 5 = 60$

Therefore, $\displaystyle GCF + LCM = 1 + 60 = 61$.

To get the answer to this question, just carefully prime factor the value $\displaystyle 3185000$:

First, $\displaystyle 3185000= 3185 * 1000$

Now, $\displaystyle 1000 = 10^3 = 2*2*2*5*5*5 = 2^35^3$ 

For $\displaystyle 3185$, begin by dividing by $\displaystyle 5$:

$\displaystyle 3185 = 5 * 637$

Now, this is a bit trickier for $\displaystyle 637$. This happens to be divisible by $\displaystyle 7$:

$\displaystyle 637 = 7 * 91$

$\displaystyle 91$ also is divisible by $\displaystyle 7$:

$\displaystyle 91 = 7 * 13$

Thus, your total answer is:

$\displaystyle 3185000 = 2^35^47^213^1$

To find the number of factors of a given number, the easiest thing to do is to make a table of the factors, starting with $\displaystyle 1$ and that number. So, for $\displaystyle 42$, we get:

$\displaystyle 1 * 42$

$\displaystyle 2*21$

$\displaystyle 3*14$

$\displaystyle 6*7$

At this point, things begin to repeat. Thus, the total number of factors is $\displaystyle 8$.

To find the number of factors of a given number, the easiest thing to do is to make a table of the factors, starting with $\displaystyle 1$ and that number. So, for $\displaystyle 60$, we get:

$\displaystyle 1*60$

$\displaystyle 2*30$

$\displaystyle 3*20$

$\displaystyle 4*15$

$\displaystyle 5*12$

$\displaystyle 6*10$

At this point, the values begin to repeat. This means that there are an even number of factors. At the "middle" of the list, we find $\displaystyle 6$ and $\displaystyle 10$. To find the median of the list, you merely need to take the average of these two numbers:

$\displaystyle \frac{6+10}{2}=\frac{16}{2}=8$
