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 455,232,205, 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 | 455,232,205 | |
| -1 | -455,232,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 455,232,205.
Example:
1 x 455,232,205 = 455,232,205
and
-1 x -455,232,205 = 455,232,205
Notice both answers equal 455,232,205
With that explanation out of the way, let's continue. Next, we take the number 455,232,205 and divide it by 2:
455,232,205 ÷ 2 = 227,616,102.5
If the quotient is a whole number, then 2 and 227,616,102.5 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 | 455,232,205 | |
| -1 | -455,232,205 |
Now, we try dividing 455,232,205 by 3:
455,232,205 ÷ 3 = 151,744,068.3333
If the quotient is a whole number, then 3 and 151,744,068.3333 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 | 455,232,205 | |
| -1 | -455,232,205 |
Let's try dividing by 4:
455,232,205 ÷ 4 = 113,808,051.25
If the quotient is a whole number, then 4 and 113,808,051.25 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 | 455,232,205 | |
| -1 | 455,232,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 131 | 655 | 2,227 | 11,135 | 40,883 | 204,415 | 695,011 | 3,475,055 | 5,355,673 | 26,778,365 | 91,046,441 | 455,232,205 |
| -1 | -5 | -17 | -85 | -131 | -655 | -2,227 | -11,135 | -40,883 | -204,415 | -695,011 | -3,475,055 | -5,355,673 | -26,778,365 | -91,046,441 | -455,232,205 |
