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 32,108,839, 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 | 32,108,839 | |
| -1 | -32,108,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,108,839.
Example:
1 x 32,108,839 = 32,108,839
and
-1 x -32,108,839 = 32,108,839
Notice both answers equal 32,108,839
With that explanation out of the way, let's continue. Next, we take the number 32,108,839 and divide it by 2:
32,108,839 ÷ 2 = 16,054,419.5
If the quotient is a whole number, then 2 and 16,054,419.5 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 | 32,108,839 | |
| -1 | -32,108,839 |
Now, we try dividing 32,108,839 by 3:
32,108,839 ÷ 3 = 10,702,946.3333
If the quotient is a whole number, then 3 and 10,702,946.3333 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 | 32,108,839 | |
| -1 | -32,108,839 |
Let's try dividing by 4:
32,108,839 ÷ 4 = 8,027,209.75
If the quotient is a whole number, then 4 and 8,027,209.75 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 | 32,108,839 | |
| -1 | 32,108,839 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 79 | 217 | 553 | 1,873 | 2,449 | 13,111 | 17,143 | 58,063 | 147,967 | 406,441 | 1,035,769 | 4,586,977 | 32,108,839 |
| -1 | -7 | -31 | -79 | -217 | -553 | -1,873 | -2,449 | -13,111 | -17,143 | -58,063 | -147,967 | -406,441 | -1,035,769 | -4,586,977 | -32,108,839 |
