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 15,948,533, 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 | 15,948,533 | |
| -1 | -15,948,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,948,533.
Example:
1 x 15,948,533 = 15,948,533
and
-1 x -15,948,533 = 15,948,533
Notice both answers equal 15,948,533
With that explanation out of the way, let's continue. Next, we take the number 15,948,533 and divide it by 2:
15,948,533 ÷ 2 = 7,974,266.5
If the quotient is a whole number, then 2 and 7,974,266.5 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 | 15,948,533 | |
| -1 | -15,948,533 |
Now, we try dividing 15,948,533 by 3:
15,948,533 ÷ 3 = 5,316,177.6667
If the quotient is a whole number, then 3 and 5,316,177.6667 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 | 15,948,533 | |
| -1 | -15,948,533 |
Let's try dividing by 4:
15,948,533 ÷ 4 = 3,987,133.25
If the quotient is a whole number, then 4 and 3,987,133.25 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 | 15,948,533 | |
| -1 | 15,948,533 |
If you did it right, you will end up with this table:
| 1 | 17 | 83 | 89 | 127 | 1,411 | 1,513 | 2,159 | 7,387 | 10,541 | 11,303 | 125,579 | 179,197 | 192,151 | 938,149 | 15,948,533 |
| -1 | -17 | -83 | -89 | -127 | -1,411 | -1,513 | -2,159 | -7,387 | -10,541 | -11,303 | -125,579 | -179,197 | -192,151 | -938,149 | -15,948,533 |
