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 455,224,025, 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 | 455,224,025 | |
| -1 | -455,224,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 455,224,025.
Example:
1 x 455,224,025 = 455,224,025
and
-1 x -455,224,025 = 455,224,025
Notice both answers equal 455,224,025
With that explanation out of the way, let's continue. Next, we take the number 455,224,025 and divide it by 2:
455,224,025 ÷ 2 = 227,612,012.5
If the quotient is a whole number, then 2 and 227,612,012.5 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 | 455,224,025 | |
| -1 | -455,224,025 |
Now, we try dividing 455,224,025 by 3:
455,224,025 ÷ 3 = 151,741,341.6667
If the quotient is a whole number, then 3 and 151,741,341.6667 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 | 455,224,025 | |
| -1 | -455,224,025 |
Let's try dividing by 4:
455,224,025 ÷ 4 = 113,806,006.25
If the quotient is a whole number, then 4 and 113,806,006.25 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 | 455,224,025 | |
| -1 | 455,224,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 205 | 1,025 | 444,121 | 2,220,605 | 11,103,025 | 18,208,961 | 91,044,805 | 455,224,025 |
| -1 | -5 | -25 | -41 | -205 | -1,025 | -444,121 | -2,220,605 | -11,103,025 | -18,208,961 | -91,044,805 | -455,224,025 |
