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 22,813,055, 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 | 22,813,055 | |
| -1 | -22,813,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,813,055.
Example:
1 x 22,813,055 = 22,813,055
and
-1 x -22,813,055 = 22,813,055
Notice both answers equal 22,813,055
With that explanation out of the way, let's continue. Next, we take the number 22,813,055 and divide it by 2:
22,813,055 ÷ 2 = 11,406,527.5
If the quotient is a whole number, then 2 and 11,406,527.5 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 | 22,813,055 | |
| -1 | -22,813,055 |
Now, we try dividing 22,813,055 by 3:
22,813,055 ÷ 3 = 7,604,351.6667
If the quotient is a whole number, then 3 and 7,604,351.6667 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 | 22,813,055 | |
| -1 | -22,813,055 |
Let's try dividing by 4:
22,813,055 ÷ 4 = 5,703,263.75
If the quotient is a whole number, then 4 and 5,703,263.75 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 | 22,813,055 | |
| -1 | 22,813,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 53 | 155 | 265 | 1,643 | 2,777 | 8,215 | 13,885 | 86,087 | 147,181 | 430,435 | 735,905 | 4,562,611 | 22,813,055 |
| -1 | -5 | -31 | -53 | -155 | -265 | -1,643 | -2,777 | -8,215 | -13,885 | -86,087 | -147,181 | -430,435 | -735,905 | -4,562,611 | -22,813,055 |
