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 22,523,137, 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 | 22,523,137 | |
| -1 | -22,523,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,523,137.
Example:
1 x 22,523,137 = 22,523,137
and
-1 x -22,523,137 = 22,523,137
Notice both answers equal 22,523,137
With that explanation out of the way, let's continue. Next, we take the number 22,523,137 and divide it by 2:
22,523,137 ÷ 2 = 11,261,568.5
If the quotient is a whole number, then 2 and 11,261,568.5 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 | 22,523,137 | |
| -1 | -22,523,137 |
Now, we try dividing 22,523,137 by 3:
22,523,137 ÷ 3 = 7,507,712.3333
If the quotient is a whole number, then 3 and 7,507,712.3333 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 | 22,523,137 | |
| -1 | -22,523,137 |
Let's try dividing by 4:
22,523,137 ÷ 4 = 5,630,784.25
If the quotient is a whole number, then 4 and 5,630,784.25 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 | 22,523,137 | |
| -1 | 22,523,137 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 79 | 91 | 169 | 241 | 553 | 1,027 | 1,183 | 1,687 | 3,133 | 7,189 | 13,351 | 19,039 | 21,931 | 40,729 | 93,457 | 133,273 | 247,507 | 285,103 | 1,732,549 | 3,217,591 | 22,523,137 |
| -1 | -7 | -13 | -79 | -91 | -169 | -241 | -553 | -1,027 | -1,183 | -1,687 | -3,133 | -7,189 | -13,351 | -19,039 | -21,931 | -40,729 | -93,457 | -133,273 | -247,507 | -285,103 | -1,732,549 | -3,217,591 | -22,523,137 |
