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 22,726,691, 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 | 22,726,691 | |
| -1 | -22,726,691 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,726,691.
Example:
1 x 22,726,691 = 22,726,691
and
-1 x -22,726,691 = 22,726,691
Notice both answers equal 22,726,691
With that explanation out of the way, let's continue. Next, we take the number 22,726,691 and divide it by 2:
22,726,691 ÷ 2 = 11,363,345.5
If the quotient is a whole number, then 2 and 11,363,345.5 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 | 22,726,691 | |
| -1 | -22,726,691 |
Now, we try dividing 22,726,691 by 3:
22,726,691 ÷ 3 = 7,575,563.6667
If the quotient is a whole number, then 3 and 7,575,563.6667 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 | 22,726,691 | |
| -1 | -22,726,691 |
Let's try dividing by 4:
22,726,691 ÷ 4 = 5,681,672.75
If the quotient is a whole number, then 4 and 5,681,672.75 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 | 22,726,691 | |
| -1 | 22,726,691 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 29 | 299 | 377 | 667 | 2,621 | 8,671 | 34,073 | 60,283 | 76,009 | 783,679 | 988,117 | 1,748,207 | 22,726,691 |
| -1 | -13 | -23 | -29 | -299 | -377 | -667 | -2,621 | -8,671 | -34,073 | -60,283 | -76,009 | -783,679 | -988,117 | -1,748,207 | -22,726,691 |
