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 34,514,515, 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 | 34,514,515 | |
| -1 | -34,514,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,514,515.
Example:
1 x 34,514,515 = 34,514,515
and
-1 x -34,514,515 = 34,514,515
Notice both answers equal 34,514,515
With that explanation out of the way, let's continue. Next, we take the number 34,514,515 and divide it by 2:
34,514,515 ÷ 2 = 17,257,257.5
If the quotient is a whole number, then 2 and 17,257,257.5 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 | 34,514,515 | |
| -1 | -34,514,515 |
Now, we try dividing 34,514,515 by 3:
34,514,515 ÷ 3 = 11,504,838.3333
If the quotient is a whole number, then 3 and 11,504,838.3333 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 | 34,514,515 | |
| -1 | -34,514,515 |
Let's try dividing by 4:
34,514,515 ÷ 4 = 8,628,628.75
If the quotient is a whole number, then 4 and 8,628,628.75 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 | 34,514,515 | |
| -1 | 34,514,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 367 | 1,835 | 2,569 | 2,687 | 12,845 | 13,435 | 18,809 | 94,045 | 986,129 | 4,930,645 | 6,902,903 | 34,514,515 |
| -1 | -5 | -7 | -35 | -367 | -1,835 | -2,569 | -2,687 | -12,845 | -13,435 | -18,809 | -94,045 | -986,129 | -4,930,645 | -6,902,903 | -34,514,515 |
