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 22,636,885, 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 | 22,636,885 | |
| -1 | -22,636,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,636,885.
Example:
1 x 22,636,885 = 22,636,885
and
-1 x -22,636,885 = 22,636,885
Notice both answers equal 22,636,885
With that explanation out of the way, let's continue. Next, we take the number 22,636,885 and divide it by 2:
22,636,885 ÷ 2 = 11,318,442.5
If the quotient is a whole number, then 2 and 11,318,442.5 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 | 22,636,885 | |
| -1 | -22,636,885 |
Now, we try dividing 22,636,885 by 3:
22,636,885 ÷ 3 = 7,545,628.3333
If the quotient is a whole number, then 3 and 7,545,628.3333 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 | 22,636,885 | |
| -1 | -22,636,885 |
Let's try dividing by 4:
22,636,885 ÷ 4 = 5,659,221.25
If the quotient is a whole number, then 4 and 5,659,221.25 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 | 22,636,885 | |
| -1 | 22,636,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 239 | 997 | 1,195 | 4,541 | 4,985 | 18,943 | 22,705 | 94,715 | 238,283 | 1,191,415 | 4,527,377 | 22,636,885 |
| -1 | -5 | -19 | -95 | -239 | -997 | -1,195 | -4,541 | -4,985 | -18,943 | -22,705 | -94,715 | -238,283 | -1,191,415 | -4,527,377 | -22,636,885 |
