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 31,646,215, 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 | 31,646,215 | |
| -1 | -31,646,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,646,215.
Example:
1 x 31,646,215 = 31,646,215
and
-1 x -31,646,215 = 31,646,215
Notice both answers equal 31,646,215
With that explanation out of the way, let's continue. Next, we take the number 31,646,215 and divide it by 2:
31,646,215 ÷ 2 = 15,823,107.5
If the quotient is a whole number, then 2 and 15,823,107.5 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 | 31,646,215 | |
| -1 | -31,646,215 |
Now, we try dividing 31,646,215 by 3:
31,646,215 ÷ 3 = 10,548,738.3333
If the quotient is a whole number, then 3 and 10,548,738.3333 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 | 31,646,215 | |
| -1 | -31,646,215 |
Let's try dividing by 4:
31,646,215 ÷ 4 = 7,911,553.75
If the quotient is a whole number, then 4 and 7,911,553.75 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 | 31,646,215 | |
| -1 | 31,646,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 113 | 395 | 565 | 709 | 3,545 | 8,927 | 44,635 | 56,011 | 80,117 | 280,055 | 400,585 | 6,329,243 | 31,646,215 |
| -1 | -5 | -79 | -113 | -395 | -565 | -709 | -3,545 | -8,927 | -44,635 | -56,011 | -80,117 | -280,055 | -400,585 | -6,329,243 | -31,646,215 |
