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 22,156,337, 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 | 22,156,337 | |
| -1 | -22,156,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,156,337.
Example:
1 x 22,156,337 = 22,156,337
and
-1 x -22,156,337 = 22,156,337
Notice both answers equal 22,156,337
With that explanation out of the way, let's continue. Next, we take the number 22,156,337 and divide it by 2:
22,156,337 ÷ 2 = 11,078,168.5
If the quotient is a whole number, then 2 and 11,078,168.5 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 | 22,156,337 | |
| -1 | -22,156,337 |
Now, we try dividing 22,156,337 by 3:
22,156,337 ÷ 3 = 7,385,445.6667
If the quotient is a whole number, then 3 and 7,385,445.6667 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 | 22,156,337 | |
| -1 | -22,156,337 |
Let's try dividing by 4:
22,156,337 ÷ 4 = 5,539,084.25
If the quotient is a whole number, then 4 and 5,539,084.25 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 | 22,156,337 | |
| -1 | 22,156,337 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 3,059 | 7,243 | 50,701 | 137,617 | 166,589 | 963,319 | 1,166,123 | 3,165,191 | 22,156,337 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -3,059 | -7,243 | -50,701 | -137,617 | -166,589 | -963,319 | -1,166,123 | -3,165,191 | -22,156,337 |
