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 34,331,215, 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 | 34,331,215 | |
| -1 | -34,331,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,331,215.
Example:
1 x 34,331,215 = 34,331,215
and
-1 x -34,331,215 = 34,331,215
Notice both answers equal 34,331,215
With that explanation out of the way, let's continue. Next, we take the number 34,331,215 and divide it by 2:
34,331,215 ÷ 2 = 17,165,607.5
If the quotient is a whole number, then 2 and 17,165,607.5 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 | 34,331,215 | |
| -1 | -34,331,215 |
Now, we try dividing 34,331,215 by 3:
34,331,215 ÷ 3 = 11,443,738.3333
If the quotient is a whole number, then 3 and 11,443,738.3333 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 | 34,331,215 | |
| -1 | -34,331,215 |
Let's try dividing by 4:
34,331,215 ÷ 4 = 8,582,803.75
If the quotient is a whole number, then 4 and 8,582,803.75 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 | 34,331,215 | |
| -1 | 34,331,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 59 | 145 | 295 | 1,711 | 4,013 | 8,555 | 20,065 | 116,377 | 236,767 | 581,885 | 1,183,835 | 6,866,243 | 34,331,215 |
| -1 | -5 | -29 | -59 | -145 | -295 | -1,711 | -4,013 | -8,555 | -20,065 | -116,377 | -236,767 | -581,885 | -1,183,835 | -6,866,243 | -34,331,215 |
