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 455,413,345, 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 | 455,413,345 | |
| -1 | -455,413,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 455,413,345.
Example:
1 x 455,413,345 = 455,413,345
and
-1 x -455,413,345 = 455,413,345
Notice both answers equal 455,413,345
With that explanation out of the way, let's continue. Next, we take the number 455,413,345 and divide it by 2:
455,413,345 ÷ 2 = 227,706,672.5
If the quotient is a whole number, then 2 and 227,706,672.5 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 | 455,413,345 | |
| -1 | -455,413,345 |
Now, we try dividing 455,413,345 by 3:
455,413,345 ÷ 3 = 151,804,448.3333
If the quotient is a whole number, then 3 and 151,804,448.3333 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 | 455,413,345 | |
| -1 | -455,413,345 |
Let's try dividing by 4:
455,413,345 ÷ 4 = 113,853,336.25
If the quotient is a whole number, then 4 and 113,853,336.25 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 | 455,413,345 | |
| -1 | 455,413,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 137 | 139 | 685 | 695 | 4,783 | 19,043 | 23,915 | 95,215 | 655,271 | 664,837 | 3,276,355 | 3,324,185 | 91,082,669 | 455,413,345 |
| -1 | -5 | -137 | -139 | -685 | -695 | -4,783 | -19,043 | -23,915 | -95,215 | -655,271 | -664,837 | -3,276,355 | -3,324,185 | -91,082,669 | -455,413,345 |
