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 32,160,073, 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 | 32,160,073 | |
| -1 | -32,160,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,160,073.
Example:
1 x 32,160,073 = 32,160,073
and
-1 x -32,160,073 = 32,160,073
Notice both answers equal 32,160,073
With that explanation out of the way, let's continue. Next, we take the number 32,160,073 and divide it by 2:
32,160,073 ÷ 2 = 16,080,036.5
If the quotient is a whole number, then 2 and 16,080,036.5 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 | 32,160,073 | |
| -1 | -32,160,073 |
Now, we try dividing 32,160,073 by 3:
32,160,073 ÷ 3 = 10,720,024.3333
If the quotient is a whole number, then 3 and 10,720,024.3333 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 | 32,160,073 | |
| -1 | -32,160,073 |
Let's try dividing by 4:
32,160,073 ÷ 4 = 8,040,018.25
If the quotient is a whole number, then 4 and 8,040,018.25 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 | 32,160,073 | |
| -1 | 32,160,073 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 229 | 751 | 2,519 | 3,893 | 8,261 | 12,767 | 42,823 | 140,437 | 171,979 | 1,891,769 | 2,923,643 | 32,160,073 |
| -1 | -11 | -17 | -187 | -229 | -751 | -2,519 | -3,893 | -8,261 | -12,767 | -42,823 | -140,437 | -171,979 | -1,891,769 | -2,923,643 | -32,160,073 |
