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 15,934,369, 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 | 15,934,369 | |
| -1 | -15,934,369 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,934,369.
Example:
1 x 15,934,369 = 15,934,369
and
-1 x -15,934,369 = 15,934,369
Notice both answers equal 15,934,369
With that explanation out of the way, let's continue. Next, we take the number 15,934,369 and divide it by 2:
15,934,369 ÷ 2 = 7,967,184.5
If the quotient is a whole number, then 2 and 7,967,184.5 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 | 15,934,369 | |
| -1 | -15,934,369 |
Now, we try dividing 15,934,369 by 3:
15,934,369 ÷ 3 = 5,311,456.3333
If the quotient is a whole number, then 3 and 5,311,456.3333 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 | 15,934,369 | |
| -1 | -15,934,369 |
Let's try dividing by 4:
15,934,369 ÷ 4 = 3,983,592.25
If the quotient is a whole number, then 4 and 3,983,592.25 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 | 15,934,369 | |
| -1 | 15,934,369 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 29 | 121 | 209 | 239 | 319 | 551 | 2,299 | 2,629 | 3,509 | 4,541 | 6,061 | 6,931 | 28,919 | 49,951 | 66,671 | 76,241 | 131,689 | 549,461 | 838,651 | 1,448,579 | 15,934,369 |
| -1 | -11 | -19 | -29 | -121 | -209 | -239 | -319 | -551 | -2,299 | -2,629 | -3,509 | -4,541 | -6,061 | -6,931 | -28,919 | -49,951 | -66,671 | -76,241 | -131,689 | -549,461 | -838,651 | -1,448,579 | -15,934,369 |
