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 412,542,403, 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 | 412,542,403 | |
| -1 | -412,542,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 412,542,403.
Example:
1 x 412,542,403 = 412,542,403
and
-1 x -412,542,403 = 412,542,403
Notice both answers equal 412,542,403
With that explanation out of the way, let's continue. Next, we take the number 412,542,403 and divide it by 2:
412,542,403 ÷ 2 = 206,271,201.5
If the quotient is a whole number, then 2 and 206,271,201.5 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 | 412,542,403 | |
| -1 | -412,542,403 |
Now, we try dividing 412,542,403 by 3:
412,542,403 ÷ 3 = 137,514,134.3333
If the quotient is a whole number, then 3 and 137,514,134.3333 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 | 412,542,403 | |
| -1 | -412,542,403 |
Let's try dividing by 4:
412,542,403 ÷ 4 = 103,135,600.75
If the quotient is a whole number, then 4 and 103,135,600.75 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 | 412,542,403 | |
| -1 | 412,542,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 1,871 | 2,423 | 13,097 | 16,961 | 24,323 | 31,499 | 170,261 | 220,493 | 4,533,433 | 31,734,031 | 58,934,629 | 412,542,403 |
| -1 | -7 | -13 | -91 | -1,871 | -2,423 | -13,097 | -16,961 | -24,323 | -31,499 | -170,261 | -220,493 | -4,533,433 | -31,734,031 | -58,934,629 | -412,542,403 |
