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 5,136,131, 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 | 5,136,131 | |
| -1 | -5,136,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,136,131.
Example:
1 x 5,136,131 = 5,136,131
and
-1 x -5,136,131 = 5,136,131
Notice both answers equal 5,136,131
With that explanation out of the way, let's continue. Next, we take the number 5,136,131 and divide it by 2:
5,136,131 ÷ 2 = 2,568,065.5
If the quotient is a whole number, then 2 and 2,568,065.5 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 | 5,136,131 | |
| -1 | -5,136,131 |
Now, we try dividing 5,136,131 by 3:
5,136,131 ÷ 3 = 1,712,043.6667
If the quotient is a whole number, then 3 and 1,712,043.6667 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 | 5,136,131 | |
| -1 | -5,136,131 |
Let's try dividing by 4:
5,136,131 ÷ 4 = 1,284,032.75
If the quotient is a whole number, then 4 and 1,284,032.75 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 | 5,136,131 | |
| -1 | 5,136,131 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 539 | 637 | 733 | 1,001 | 5,131 | 7,007 | 8,063 | 9,529 | 35,917 | 56,441 | 66,703 | 104,819 | 395,087 | 466,921 | 733,733 | 5,136,131 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -539 | -637 | -733 | -1,001 | -5,131 | -7,007 | -8,063 | -9,529 | -35,917 | -56,441 | -66,703 | -104,819 | -395,087 | -466,921 | -733,733 | -5,136,131 |
