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 32,401,435, 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 | 32,401,435 | |
| -1 | -32,401,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,401,435.
Example:
1 x 32,401,435 = 32,401,435
and
-1 x -32,401,435 = 32,401,435
Notice both answers equal 32,401,435
With that explanation out of the way, let's continue. Next, we take the number 32,401,435 and divide it by 2:
32,401,435 ÷ 2 = 16,200,717.5
If the quotient is a whole number, then 2 and 16,200,717.5 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 | 32,401,435 | |
| -1 | -32,401,435 |
Now, we try dividing 32,401,435 by 3:
32,401,435 ÷ 3 = 10,800,478.3333
If the quotient is a whole number, then 3 and 10,800,478.3333 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 | 32,401,435 | |
| -1 | -32,401,435 |
Let's try dividing by 4:
32,401,435 ÷ 4 = 8,100,358.75
If the quotient is a whole number, then 4 and 8,100,358.75 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 | 32,401,435 | |
| -1 | 32,401,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 577 | 1,021 | 2,885 | 5,105 | 6,347 | 11,231 | 31,735 | 56,155 | 589,117 | 2,945,585 | 6,480,287 | 32,401,435 |
| -1 | -5 | -11 | -55 | -577 | -1,021 | -2,885 | -5,105 | -6,347 | -11,231 | -31,735 | -56,155 | -589,117 | -2,945,585 | -6,480,287 | -32,401,435 |
