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 32,888,639, 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 | 32,888,639 | |
| -1 | -32,888,639 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,888,639.
Example:
1 x 32,888,639 = 32,888,639
and
-1 x -32,888,639 = 32,888,639
Notice both answers equal 32,888,639
With that explanation out of the way, let's continue. Next, we take the number 32,888,639 and divide it by 2:
32,888,639 ÷ 2 = 16,444,319.5
If the quotient is a whole number, then 2 and 16,444,319.5 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 | 32,888,639 | |
| -1 | -32,888,639 |
Now, we try dividing 32,888,639 by 3:
32,888,639 ÷ 3 = 10,962,879.6667
If the quotient is a whole number, then 3 and 10,962,879.6667 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 | 32,888,639 | |
| -1 | -32,888,639 |
Let's try dividing by 4:
32,888,639 ÷ 4 = 8,222,159.75
If the quotient is a whole number, then 4 and 8,222,159.75 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 | 32,888,639 | |
| -1 | 32,888,639 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 29 | 133 | 203 | 551 | 3,857 | 8,527 | 59,689 | 162,013 | 247,283 | 1,134,091 | 1,730,981 | 4,698,377 | 32,888,639 |
| -1 | -7 | -19 | -29 | -133 | -203 | -551 | -3,857 | -8,527 | -59,689 | -162,013 | -247,283 | -1,134,091 | -1,730,981 | -4,698,377 | -32,888,639 |
