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 34,231,421, 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 | 34,231,421 | |
| -1 | -34,231,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,231,421.
Example:
1 x 34,231,421 = 34,231,421
and
-1 x -34,231,421 = 34,231,421
Notice both answers equal 34,231,421
With that explanation out of the way, let's continue. Next, we take the number 34,231,421 and divide it by 2:
34,231,421 ÷ 2 = 17,115,710.5
If the quotient is a whole number, then 2 and 17,115,710.5 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 | 34,231,421 | |
| -1 | -34,231,421 |
Now, we try dividing 34,231,421 by 3:
34,231,421 ÷ 3 = 11,410,473.6667
If the quotient is a whole number, then 3 and 11,410,473.6667 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 | 34,231,421 | |
| -1 | -34,231,421 |
Let's try dividing by 4:
34,231,421 ÷ 4 = 8,557,855.25
If the quotient is a whole number, then 4 and 8,557,855.25 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 | 34,231,421 | |
| -1 | 34,231,421 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 307 | 937 | 2,149 | 5,219 | 6,559 | 15,929 | 36,533 | 111,503 | 287,659 | 2,013,613 | 4,890,203 | 34,231,421 |
| -1 | -7 | -17 | -119 | -307 | -937 | -2,149 | -5,219 | -6,559 | -15,929 | -36,533 | -111,503 | -287,659 | -2,013,613 | -4,890,203 | -34,231,421 |
