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 22,126,247, 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 | 22,126,247 | |
| -1 | -22,126,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,126,247.
Example:
1 x 22,126,247 = 22,126,247
and
-1 x -22,126,247 = 22,126,247
Notice both answers equal 22,126,247
With that explanation out of the way, let's continue. Next, we take the number 22,126,247 and divide it by 2:
22,126,247 ÷ 2 = 11,063,123.5
If the quotient is a whole number, then 2 and 11,063,123.5 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 | 22,126,247 | |
| -1 | -22,126,247 |
Now, we try dividing 22,126,247 by 3:
22,126,247 ÷ 3 = 7,375,415.6667
If the quotient is a whole number, then 3 and 7,375,415.6667 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 | 22,126,247 | |
| -1 | -22,126,247 |
Let's try dividing by 4:
22,126,247 ÷ 4 = 5,531,561.75
If the quotient is a whole number, then 4 and 5,531,561.75 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 | 22,126,247 | |
| -1 | 22,126,247 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 359 | 431 | 3,949 | 4,667 | 4,741 | 5,603 | 51,337 | 61,633 | 154,729 | 1,702,019 | 2,011,477 | 22,126,247 |
| -1 | -11 | -13 | -143 | -359 | -431 | -3,949 | -4,667 | -4,741 | -5,603 | -51,337 | -61,633 | -154,729 | -1,702,019 | -2,011,477 | -22,126,247 |
