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 32,971,565, 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 | 32,971,565 | |
| -1 | -32,971,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,971,565.
Example:
1 x 32,971,565 = 32,971,565
and
-1 x -32,971,565 = 32,971,565
Notice both answers equal 32,971,565
With that explanation out of the way, let's continue. Next, we take the number 32,971,565 and divide it by 2:
32,971,565 ÷ 2 = 16,485,782.5
If the quotient is a whole number, then 2 and 16,485,782.5 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 | 32,971,565 | |
| -1 | -32,971,565 |
Now, we try dividing 32,971,565 by 3:
32,971,565 ÷ 3 = 10,990,521.6667
If the quotient is a whole number, then 3 and 10,990,521.6667 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 | 32,971,565 | |
| -1 | -32,971,565 |
Let's try dividing by 4:
32,971,565 ÷ 4 = 8,242,891.25
If the quotient is a whole number, then 4 and 8,242,891.25 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 | 32,971,565 | |
| -1 | 32,971,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 11,311 | 56,555 | 124,421 | 599,483 | 622,105 | 2,997,415 | 6,594,313 | 32,971,565 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -11,311 | -56,555 | -124,421 | -599,483 | -622,105 | -2,997,415 | -6,594,313 | -32,971,565 |
