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

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 and that number. So, for , we get:

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 and . To find the median of the list, you merely need to take the average of these two numbers:

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

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

To get the answer to this question, just carefully prime factor the value :

First,

Now,

For , begin by dividing by :

Now, this is a bit trickier for . This happens to be divisible by :

also is divisible by :

Thus, your total answer is:

Thus, your total answer is:

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