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 4,013,513, 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 | 4,013,513 | |
| -1 | -4,013,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,013,513.
Example:
1 x 4,013,513 = 4,013,513
and
-1 x -4,013,513 = 4,013,513
Notice both answers equal 4,013,513
With that explanation out of the way, let's continue. Next, we take the number 4,013,513 and divide it by 2:
4,013,513 ÷ 2 = 2,006,756.5
If the quotient is a whole number, then 2 and 2,006,756.5 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 | 4,013,513 | |
| -1 | -4,013,513 |
Now, we try dividing 4,013,513 by 3:
4,013,513 ÷ 3 = 1,337,837.6667
If the quotient is a whole number, then 3 and 1,337,837.6667 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 | 4,013,513 | |
| -1 | -4,013,513 |
Let's try dividing by 4:
4,013,513 ÷ 4 = 1,003,378.25
If the quotient is a whole number, then 4 and 1,003,378.25 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 | 4,013,513 | |
| -1 | 4,013,513 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 29 | 119 | 203 | 493 | 1,163 | 3,451 | 8,141 | 19,771 | 33,727 | 138,397 | 236,089 | 573,359 | 4,013,513 |
| -1 | -7 | -17 | -29 | -119 | -203 | -493 | -1,163 | -3,451 | -8,141 | -19,771 | -33,727 | -138,397 | -236,089 | -573,359 | -4,013,513 |
