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 22,329,427, 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 | 22,329,427 | |
| -1 | -22,329,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,329,427.
Example:
1 x 22,329,427 = 22,329,427
and
-1 x -22,329,427 = 22,329,427
Notice both answers equal 22,329,427
With that explanation out of the way, let's continue. Next, we take the number 22,329,427 and divide it by 2:
22,329,427 ÷ 2 = 11,164,713.5
If the quotient is a whole number, then 2 and 11,164,713.5 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 | 22,329,427 | |
| -1 | -22,329,427 |
Now, we try dividing 22,329,427 by 3:
22,329,427 ÷ 3 = 7,443,142.3333
If the quotient is a whole number, then 3 and 7,443,142.3333 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 | 22,329,427 | |
| -1 | -22,329,427 |
Let's try dividing by 4:
22,329,427 ÷ 4 = 5,582,356.75
If the quotient is a whole number, then 4 and 5,582,356.75 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 | 22,329,427 | |
| -1 | 22,329,427 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 151 | 181 | 817 | 2,869 | 3,439 | 6,493 | 7,783 | 27,331 | 123,367 | 147,877 | 519,289 | 1,175,233 | 22,329,427 |
| -1 | -19 | -43 | -151 | -181 | -817 | -2,869 | -3,439 | -6,493 | -7,783 | -27,331 | -123,367 | -147,877 | -519,289 | -1,175,233 | -22,329,427 |
