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 22,617,287, 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 | 22,617,287 | |
| -1 | -22,617,287 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,617,287.
Example:
1 x 22,617,287 = 22,617,287
and
-1 x -22,617,287 = 22,617,287
Notice both answers equal 22,617,287
With that explanation out of the way, let's continue. Next, we take the number 22,617,287 and divide it by 2:
22,617,287 ÷ 2 = 11,308,643.5
If the quotient is a whole number, then 2 and 11,308,643.5 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 | 22,617,287 | |
| -1 | -22,617,287 |
Now, we try dividing 22,617,287 by 3:
22,617,287 ÷ 3 = 7,539,095.6667
If the quotient is a whole number, then 3 and 7,539,095.6667 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 | 22,617,287 | |
| -1 | -22,617,287 |
Let's try dividing by 4:
22,617,287 ÷ 4 = 5,654,321.75
If the quotient is a whole number, then 4 and 5,654,321.75 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 | 22,617,287 | |
| -1 | 22,617,287 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 239 | 1,229 | 1,673 | 2,629 | 8,603 | 13,519 | 18,403 | 94,633 | 293,731 | 2,056,117 | 3,231,041 | 22,617,287 |
| -1 | -7 | -11 | -77 | -239 | -1,229 | -1,673 | -2,629 | -8,603 | -13,519 | -18,403 | -94,633 | -293,731 | -2,056,117 | -3,231,041 | -22,617,287 |
