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 22,143,401, 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 | 22,143,401 | |
| -1 | -22,143,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,143,401.
Example:
1 x 22,143,401 = 22,143,401
and
-1 x -22,143,401 = 22,143,401
Notice both answers equal 22,143,401
With that explanation out of the way, let's continue. Next, we take the number 22,143,401 and divide it by 2:
22,143,401 ÷ 2 = 11,071,700.5
If the quotient is a whole number, then 2 and 11,071,700.5 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 | 22,143,401 | |
| -1 | -22,143,401 |
Now, we try dividing 22,143,401 by 3:
22,143,401 ÷ 3 = 7,381,133.6667
If the quotient is a whole number, then 3 and 7,381,133.6667 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 | 22,143,401 | |
| -1 | -22,143,401 |
Let's try dividing by 4:
22,143,401 ÷ 4 = 5,535,850.25
If the quotient is a whole number, then 4 and 5,535,850.25 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 | 22,143,401 | |
| -1 | 22,143,401 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 317 | 587 | 2,219 | 4,109 | 5,389 | 9,979 | 37,723 | 69,853 | 186,079 | 1,302,553 | 3,163,343 | 22,143,401 |
| -1 | -7 | -17 | -119 | -317 | -587 | -2,219 | -4,109 | -5,389 | -9,979 | -37,723 | -69,853 | -186,079 | -1,302,553 | -3,163,343 | -22,143,401 |
