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 23,156,635, 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 | 23,156,635 | |
| -1 | -23,156,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,156,635.
Example:
1 x 23,156,635 = 23,156,635
and
-1 x -23,156,635 = 23,156,635
Notice both answers equal 23,156,635
With that explanation out of the way, let's continue. Next, we take the number 23,156,635 and divide it by 2:
23,156,635 ÷ 2 = 11,578,317.5
If the quotient is a whole number, then 2 and 11,578,317.5 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 | 23,156,635 | |
| -1 | -23,156,635 |
Now, we try dividing 23,156,635 by 3:
23,156,635 ÷ 3 = 7,718,878.3333
If the quotient is a whole number, then 3 and 7,718,878.3333 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 | 23,156,635 | |
| -1 | -23,156,635 |
Let's try dividing by 4:
23,156,635 ÷ 4 = 5,789,158.75
If the quotient is a whole number, then 4 and 5,789,158.75 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 | 23,156,635 | |
| -1 | 23,156,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 199 | 629 | 995 | 1,369 | 3,145 | 3,383 | 6,845 | 7,363 | 16,915 | 23,273 | 36,815 | 116,365 | 125,171 | 272,431 | 625,855 | 1,362,155 | 4,631,327 | 23,156,635 |
| -1 | -5 | -17 | -37 | -85 | -185 | -199 | -629 | -995 | -1,369 | -3,145 | -3,383 | -6,845 | -7,363 | -16,915 | -23,273 | -36,815 | -116,365 | -125,171 | -272,431 | -625,855 | -1,362,155 | -4,631,327 | -23,156,635 |
