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 22,220,003, 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 | 22,220,003 | |
| -1 | -22,220,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,220,003.
Example:
1 x 22,220,003 = 22,220,003
and
-1 x -22,220,003 = 22,220,003
Notice both answers equal 22,220,003
With that explanation out of the way, let's continue. Next, we take the number 22,220,003 and divide it by 2:
22,220,003 ÷ 2 = 11,110,001.5
If the quotient is a whole number, then 2 and 11,110,001.5 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 | 22,220,003 | |
| -1 | -22,220,003 |
Now, we try dividing 22,220,003 by 3:
22,220,003 ÷ 3 = 7,406,667.6667
If the quotient is a whole number, then 3 and 7,406,667.6667 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 | 22,220,003 | |
| -1 | -22,220,003 |
Let's try dividing by 4:
22,220,003 ÷ 4 = 5,555,000.75
If the quotient is a whole number, then 4 and 5,555,000.75 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 | 22,220,003 | |
| -1 | 22,220,003 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 29 | 221 | 377 | 493 | 3,467 | 6,409 | 45,071 | 58,939 | 100,543 | 766,207 | 1,307,059 | 1,709,231 | 22,220,003 |
| -1 | -13 | -17 | -29 | -221 | -377 | -493 | -3,467 | -6,409 | -45,071 | -58,939 | -100,543 | -766,207 | -1,307,059 | -1,709,231 | -22,220,003 |
