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 412,625,635, 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 | 412,625,635 | |
| -1 | -412,625,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 412,625,635.
Example:
1 x 412,625,635 = 412,625,635
and
-1 x -412,625,635 = 412,625,635
Notice both answers equal 412,625,635
With that explanation out of the way, let's continue. Next, we take the number 412,625,635 and divide it by 2:
412,625,635 ÷ 2 = 206,312,817.5
If the quotient is a whole number, then 2 and 206,312,817.5 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 | 412,625,635 | |
| -1 | -412,625,635 |
Now, we try dividing 412,625,635 by 3:
412,625,635 ÷ 3 = 137,541,878.3333
If the quotient is a whole number, then 3 and 137,541,878.3333 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 | 412,625,635 | |
| -1 | -412,625,635 |
Let's try dividing by 4:
412,625,635 ÷ 4 = 103,156,408.75
If the quotient is a whole number, then 4 and 103,156,408.75 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 | 412,625,635 | |
| -1 | 412,625,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 989 | 4,945 | 83,443 | 417,215 | 1,919,189 | 3,588,049 | 9,595,945 | 17,940,245 | 82,525,127 | 412,625,635 |
| -1 | -5 | -23 | -43 | -115 | -215 | -989 | -4,945 | -83,443 | -417,215 | -1,919,189 | -3,588,049 | -9,595,945 | -17,940,245 | -82,525,127 | -412,625,635 |
