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 32,777,507, 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 | 32,777,507 | |
| -1 | -32,777,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,777,507.
Example:
1 x 32,777,507 = 32,777,507
and
-1 x -32,777,507 = 32,777,507
Notice both answers equal 32,777,507
With that explanation out of the way, let's continue. Next, we take the number 32,777,507 and divide it by 2:
32,777,507 ÷ 2 = 16,388,753.5
If the quotient is a whole number, then 2 and 16,388,753.5 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 | 32,777,507 | |
| -1 | -32,777,507 |
Now, we try dividing 32,777,507 by 3:
32,777,507 ÷ 3 = 10,925,835.6667
If the quotient is a whole number, then 3 and 10,925,835.6667 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 | 32,777,507 | |
| -1 | -32,777,507 |
Let's try dividing by 4:
32,777,507 ÷ 4 = 8,194,376.75
If the quotient is a whole number, then 4 and 8,194,376.75 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 | 32,777,507 | |
| -1 | 32,777,507 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 163 | 1,141 | 1,249 | 3,749 | 8,743 | 26,243 | 28,727 | 201,089 | 203,587 | 1,425,109 | 4,682,501 | 32,777,507 |
| -1 | -7 | -23 | -161 | -163 | -1,141 | -1,249 | -3,749 | -8,743 | -26,243 | -28,727 | -201,089 | -203,587 | -1,425,109 | -4,682,501 | -32,777,507 |
