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 34,323,215, 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 | 34,323,215 | |
| -1 | -34,323,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,323,215.
Example:
1 x 34,323,215 = 34,323,215
and
-1 x -34,323,215 = 34,323,215
Notice both answers equal 34,323,215
With that explanation out of the way, let's continue. Next, we take the number 34,323,215 and divide it by 2:
34,323,215 ÷ 2 = 17,161,607.5
If the quotient is a whole number, then 2 and 17,161,607.5 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 | 34,323,215 | |
| -1 | -34,323,215 |
Now, we try dividing 34,323,215 by 3:
34,323,215 ÷ 3 = 11,441,071.6667
If the quotient is a whole number, then 3 and 11,441,071.6667 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 | 34,323,215 | |
| -1 | -34,323,215 |
Let's try dividing by 4:
34,323,215 ÷ 4 = 8,580,803.75
If the quotient is a whole number, then 4 and 8,580,803.75 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 | 34,323,215 | |
| -1 | 34,323,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 439 | 823 | 2,195 | 4,115 | 8,341 | 15,637 | 41,705 | 78,185 | 361,297 | 1,806,485 | 6,864,643 | 34,323,215 |
| -1 | -5 | -19 | -95 | -439 | -823 | -2,195 | -4,115 | -8,341 | -15,637 | -41,705 | -78,185 | -361,297 | -1,806,485 | -6,864,643 | -34,323,215 |
