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 13,162,303, 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 | 13,162,303 | |
| -1 | -13,162,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,162,303.
Example:
1 x 13,162,303 = 13,162,303
and
-1 x -13,162,303 = 13,162,303
Notice both answers equal 13,162,303
With that explanation out of the way, let's continue. Next, we take the number 13,162,303 and divide it by 2:
13,162,303 ÷ 2 = 6,581,151.5
If the quotient is a whole number, then 2 and 6,581,151.5 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 | 13,162,303 | |
| -1 | -13,162,303 |
Now, we try dividing 13,162,303 by 3:
13,162,303 ÷ 3 = 4,387,434.3333
If the quotient is a whole number, then 3 and 4,387,434.3333 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 | 13,162,303 | |
| -1 | -13,162,303 |
Let's try dividing by 4:
13,162,303 ÷ 4 = 3,290,575.75
If the quotient is a whole number, then 4 and 3,290,575.75 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 | 13,162,303 | |
| -1 | 13,162,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 3,619 | 3,637 | 25,459 | 40,007 | 170,939 | 280,049 | 1,196,573 | 1,880,329 | 13,162,303 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -3,619 | -3,637 | -25,459 | -40,007 | -170,939 | -280,049 | -1,196,573 | -1,880,329 | -13,162,303 |
