Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 13,033,601, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 13,033,601 | |
| -1 | -13,033,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,033,601.
Example:
1 x 13,033,601 = 13,033,601
and
-1 x -13,033,601 = 13,033,601
Notice both answers equal 13,033,601
With that explanation out of the way, let's continue. Next, we take the number 13,033,601 and divide it by 2:
13,033,601 ÷ 2 = 6,516,800.5
If the quotient is a whole number, then 2 and 6,516,800.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,033,601 | |
| -1 | -13,033,601 |
Now, we try dividing 13,033,601 by 3:
13,033,601 ÷ 3 = 4,344,533.6667
If the quotient is a whole number, then 3 and 4,344,533.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,033,601 | |
| -1 | -13,033,601 |
Let's try dividing by 4:
13,033,601 ÷ 4 = 3,258,400.25
If the quotient is a whole number, then 4 and 3,258,400.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,033,601 | |
| -1 | 13,033,601 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 53 | 133 | 301 | 371 | 817 | 1,007 | 1,849 | 2,279 | 5,719 | 7,049 | 12,943 | 15,953 | 35,131 | 43,301 | 97,997 | 245,917 | 303,107 | 685,979 | 1,861,943 | 13,033,601 |
| -1 | -7 | -19 | -43 | -53 | -133 | -301 | -371 | -817 | -1,007 | -1,849 | -2,279 | -5,719 | -7,049 | -12,943 | -15,953 | -35,131 | -43,301 | -97,997 | -245,917 | -303,107 | -685,979 | -1,861,943 | -13,033,601 |
