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 31,934,635, 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 | 31,934,635 | |
| -1 | -31,934,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,934,635.
Example:
1 x 31,934,635 = 31,934,635
and
-1 x -31,934,635 = 31,934,635
Notice both answers equal 31,934,635
With that explanation out of the way, let's continue. Next, we take the number 31,934,635 and divide it by 2:
31,934,635 ÷ 2 = 15,967,317.5
If the quotient is a whole number, then 2 and 15,967,317.5 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 | 31,934,635 | |
| -1 | -31,934,635 |
Now, we try dividing 31,934,635 by 3:
31,934,635 ÷ 3 = 10,644,878.3333
If the quotient is a whole number, then 3 and 10,644,878.3333 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 | 31,934,635 | |
| -1 | -31,934,635 |
Let's try dividing by 4:
31,934,635 ÷ 4 = 7,983,658.75
If the quotient is a whole number, then 4 and 7,983,658.75 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 | 31,934,635 | |
| -1 | 31,934,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 103 | 295 | 515 | 1,051 | 5,255 | 6,077 | 30,385 | 62,009 | 108,253 | 310,045 | 541,265 | 6,386,927 | 31,934,635 |
| -1 | -5 | -59 | -103 | -295 | -515 | -1,051 | -5,255 | -6,077 | -30,385 | -62,009 | -108,253 | -310,045 | -541,265 | -6,386,927 | -31,934,635 |
