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 32,639,555, 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 | 32,639,555 | |
| -1 | -32,639,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,639,555.
Example:
1 x 32,639,555 = 32,639,555
and
-1 x -32,639,555 = 32,639,555
Notice both answers equal 32,639,555
With that explanation out of the way, let's continue. Next, we take the number 32,639,555 and divide it by 2:
32,639,555 ÷ 2 = 16,319,777.5
If the quotient is a whole number, then 2 and 16,319,777.5 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 | 32,639,555 | |
| -1 | -32,639,555 |
Now, we try dividing 32,639,555 by 3:
32,639,555 ÷ 3 = 10,879,851.6667
If the quotient is a whole number, then 3 and 10,879,851.6667 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 | 32,639,555 | |
| -1 | -32,639,555 |
Let's try dividing by 4:
32,639,555 ÷ 4 = 8,159,888.75
If the quotient is a whole number, then 4 and 8,159,888.75 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 | 32,639,555 | |
| -1 | 32,639,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 281 | 1,405 | 1,787 | 3,653 | 8,935 | 18,265 | 23,231 | 116,155 | 502,147 | 2,510,735 | 6,527,911 | 32,639,555 |
| -1 | -5 | -13 | -65 | -281 | -1,405 | -1,787 | -3,653 | -8,935 | -18,265 | -23,231 | -116,155 | -502,147 | -2,510,735 | -6,527,911 | -32,639,555 |
