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 15,759,293, 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 | 15,759,293 | |
| -1 | -15,759,293 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,759,293.
Example:
1 x 15,759,293 = 15,759,293
and
-1 x -15,759,293 = 15,759,293
Notice both answers equal 15,759,293
With that explanation out of the way, let's continue. Next, we take the number 15,759,293 and divide it by 2:
15,759,293 ÷ 2 = 7,879,646.5
If the quotient is a whole number, then 2 and 7,879,646.5 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 | 15,759,293 | |
| -1 | -15,759,293 |
Now, we try dividing 15,759,293 by 3:
15,759,293 ÷ 3 = 5,253,097.6667
If the quotient is a whole number, then 3 and 5,253,097.6667 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 | 15,759,293 | |
| -1 | -15,759,293 |
Let's try dividing by 4:
15,759,293 ÷ 4 = 3,939,823.25
If the quotient is a whole number, then 4 and 3,939,823.25 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 | 15,759,293 | |
| -1 | 15,759,293 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 83 | 421 | 451 | 913 | 3,403 | 4,631 | 17,261 | 34,943 | 37,433 | 189,871 | 384,373 | 1,432,663 | 15,759,293 |
| -1 | -11 | -41 | -83 | -421 | -451 | -913 | -3,403 | -4,631 | -17,261 | -34,943 | -37,433 | -189,871 | -384,373 | -1,432,663 | -15,759,293 |
