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 22,216,271, 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 | 22,216,271 | |
| -1 | -22,216,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,216,271.
Example:
1 x 22,216,271 = 22,216,271
and
-1 x -22,216,271 = 22,216,271
Notice both answers equal 22,216,271
With that explanation out of the way, let's continue. Next, we take the number 22,216,271 and divide it by 2:
22,216,271 ÷ 2 = 11,108,135.5
If the quotient is a whole number, then 2 and 11,108,135.5 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 | 22,216,271 | |
| -1 | -22,216,271 |
Now, we try dividing 22,216,271 by 3:
22,216,271 ÷ 3 = 7,405,423.6667
If the quotient is a whole number, then 3 and 7,405,423.6667 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 | 22,216,271 | |
| -1 | -22,216,271 |
Let's try dividing by 4:
22,216,271 ÷ 4 = 5,554,067.75
If the quotient is a whole number, then 4 and 5,554,067.75 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 | 22,216,271 | |
| -1 | 22,216,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 109 | 763 | 1,199 | 2,647 | 8,393 | 18,529 | 29,117 | 203,819 | 288,523 | 2,019,661 | 3,173,753 | 22,216,271 |
| -1 | -7 | -11 | -77 | -109 | -763 | -1,199 | -2,647 | -8,393 | -18,529 | -29,117 | -203,819 | -288,523 | -2,019,661 | -3,173,753 | -22,216,271 |
