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 32,223,715, 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 | 32,223,715 | |
| -1 | -32,223,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,223,715.
Example:
1 x 32,223,715 = 32,223,715
and
-1 x -32,223,715 = 32,223,715
Notice both answers equal 32,223,715
With that explanation out of the way, let's continue. Next, we take the number 32,223,715 and divide it by 2:
32,223,715 ÷ 2 = 16,111,857.5
If the quotient is a whole number, then 2 and 16,111,857.5 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 | 32,223,715 | |
| -1 | -32,223,715 |
Now, we try dividing 32,223,715 by 3:
32,223,715 ÷ 3 = 10,741,238.3333
If the quotient is a whole number, then 3 and 10,741,238.3333 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 | 32,223,715 | |
| -1 | -32,223,715 |
Let's try dividing by 4:
32,223,715 ÷ 4 = 8,055,928.75
If the quotient is a whole number, then 4 and 8,055,928.75 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 | 32,223,715 | |
| -1 | 32,223,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 431 | 787 | 2,155 | 3,935 | 8,189 | 14,953 | 40,945 | 74,765 | 339,197 | 1,695,985 | 6,444,743 | 32,223,715 |
| -1 | -5 | -19 | -95 | -431 | -787 | -2,155 | -3,935 | -8,189 | -14,953 | -40,945 | -74,765 | -339,197 | -1,695,985 | -6,444,743 | -32,223,715 |
