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 13,516,601, 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 | 13,516,601 | |
| -1 | -13,516,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,516,601.
Example:
1 x 13,516,601 = 13,516,601
and
-1 x -13,516,601 = 13,516,601
Notice both answers equal 13,516,601
With that explanation out of the way, let's continue. Next, we take the number 13,516,601 and divide it by 2:
13,516,601 ÷ 2 = 6,758,300.5
If the quotient is a whole number, then 2 and 6,758,300.5 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 | 13,516,601 | |
| -1 | -13,516,601 |
Now, we try dividing 13,516,601 by 3:
13,516,601 ÷ 3 = 4,505,533.6667
If the quotient is a whole number, then 3 and 4,505,533.6667 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 | 13,516,601 | |
| -1 | -13,516,601 |
Let's try dividing by 4:
13,516,601 ÷ 4 = 3,379,150.25
If the quotient is a whole number, then 4 and 3,379,150.25 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 | 13,516,601 | |
| -1 | 13,516,601 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 157 | 251 | 343 | 1,099 | 1,757 | 7,693 | 12,299 | 39,407 | 53,851 | 86,093 | 275,849 | 1,930,943 | 13,516,601 |
| -1 | -7 | -49 | -157 | -251 | -343 | -1,099 | -1,757 | -7,693 | -12,299 | -39,407 | -53,851 | -86,093 | -275,849 | -1,930,943 | -13,516,601 |
