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 22,220,401, 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 | 22,220,401 | |
| -1 | -22,220,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,220,401.
Example:
1 x 22,220,401 = 22,220,401
and
-1 x -22,220,401 = 22,220,401
Notice both answers equal 22,220,401
With that explanation out of the way, let's continue. Next, we take the number 22,220,401 and divide it by 2:
22,220,401 ÷ 2 = 11,110,200.5
If the quotient is a whole number, then 2 and 11,110,200.5 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 | 22,220,401 | |
| -1 | -22,220,401 |
Now, we try dividing 22,220,401 by 3:
22,220,401 ÷ 3 = 7,406,800.3333
If the quotient is a whole number, then 3 and 7,406,800.3333 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 | 22,220,401 | |
| -1 | -22,220,401 |
Let's try dividing by 4:
22,220,401 ÷ 4 = 5,555,100.25
If the quotient is a whole number, then 4 and 5,555,100.25 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 | 22,220,401 | |
| -1 | 22,220,401 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 139 | 287 | 557 | 973 | 3,899 | 5,699 | 22,837 | 39,893 | 77,423 | 159,859 | 541,961 | 3,174,343 | 22,220,401 |
| -1 | -7 | -41 | -139 | -287 | -557 | -973 | -3,899 | -5,699 | -22,837 | -39,893 | -77,423 | -159,859 | -541,961 | -3,174,343 | -22,220,401 |
