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 22,281,545, 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 | 22,281,545 | |
| -1 | -22,281,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,281,545.
Example:
1 x 22,281,545 = 22,281,545
and
-1 x -22,281,545 = 22,281,545
Notice both answers equal 22,281,545
With that explanation out of the way, let's continue. Next, we take the number 22,281,545 and divide it by 2:
22,281,545 ÷ 2 = 11,140,772.5
If the quotient is a whole number, then 2 and 11,140,772.5 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 | 22,281,545 | |
| -1 | -22,281,545 |
Now, we try dividing 22,281,545 by 3:
22,281,545 ÷ 3 = 7,427,181.6667
If the quotient is a whole number, then 3 and 7,427,181.6667 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 | 22,281,545 | |
| -1 | -22,281,545 |
Let's try dividing by 4:
22,281,545 ÷ 4 = 5,570,386.25
If the quotient is a whole number, then 4 and 5,570,386.25 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 | 22,281,545 | |
| -1 | 22,281,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 121 | 143 | 605 | 715 | 1,573 | 2,833 | 7,865 | 14,165 | 31,163 | 36,829 | 155,815 | 184,145 | 342,793 | 405,119 | 1,713,965 | 2,025,595 | 4,456,309 | 22,281,545 |
| -1 | -5 | -11 | -13 | -55 | -65 | -121 | -143 | -605 | -715 | -1,573 | -2,833 | -7,865 | -14,165 | -31,163 | -36,829 | -155,815 | -184,145 | -342,793 | -405,119 | -1,713,965 | -2,025,595 | -4,456,309 | -22,281,545 |
