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 22,903,531, 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 | 22,903,531 | |
| -1 | -22,903,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,903,531.
Example:
1 x 22,903,531 = 22,903,531
and
-1 x -22,903,531 = 22,903,531
Notice both answers equal 22,903,531
With that explanation out of the way, let's continue. Next, we take the number 22,903,531 and divide it by 2:
22,903,531 ÷ 2 = 11,451,765.5
If the quotient is a whole number, then 2 and 11,451,765.5 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 | 22,903,531 | |
| -1 | -22,903,531 |
Now, we try dividing 22,903,531 by 3:
22,903,531 ÷ 3 = 7,634,510.3333
If the quotient is a whole number, then 3 and 7,634,510.3333 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 | 22,903,531 | |
| -1 | -22,903,531 |
Let's try dividing by 4:
22,903,531 ÷ 4 = 5,725,882.75
If the quotient is a whole number, then 4 and 5,725,882.75 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 | 22,903,531 | |
| -1 | 22,903,531 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 73 | 133 | 337 | 511 | 931 | 1,387 | 2,359 | 3,577 | 6,403 | 9,709 | 16,513 | 24,601 | 44,821 | 67,963 | 172,207 | 313,747 | 467,419 | 1,205,449 | 3,271,933 | 22,903,531 |
| -1 | -7 | -19 | -49 | -73 | -133 | -337 | -511 | -931 | -1,387 | -2,359 | -3,577 | -6,403 | -9,709 | -16,513 | -24,601 | -44,821 | -67,963 | -172,207 | -313,747 | -467,419 | -1,205,449 | -3,271,933 | -22,903,531 |
