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 454,036,661, 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 | 454,036,661 | |
| -1 | -454,036,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 454,036,661.
Example:
1 x 454,036,661 = 454,036,661
and
-1 x -454,036,661 = 454,036,661
Notice both answers equal 454,036,661
With that explanation out of the way, let's continue. Next, we take the number 454,036,661 and divide it by 2:
454,036,661 ÷ 2 = 227,018,330.5
If the quotient is a whole number, then 2 and 227,018,330.5 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 | 454,036,661 | |
| -1 | -454,036,661 |
Now, we try dividing 454,036,661 by 3:
454,036,661 ÷ 3 = 151,345,553.6667
If the quotient is a whole number, then 3 and 151,345,553.6667 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 | 454,036,661 | |
| -1 | -454,036,661 |
Let's try dividing by 4:
454,036,661 ÷ 4 = 113,509,165.25
If the quotient is a whole number, then 4 and 113,509,165.25 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 | 454,036,661 | |
| -1 | 454,036,661 |
If you did it right, you will end up with this table:
| 1 | 13 | 251 | 347 | 401 | 3,263 | 4,511 | 5,213 | 87,097 | 100,651 | 139,147 | 1,132,261 | 1,308,463 | 1,808,911 | 34,925,897 | 454,036,661 |
| -1 | -13 | -251 | -347 | -401 | -3,263 | -4,511 | -5,213 | -87,097 | -100,651 | -139,147 | -1,132,261 | -1,308,463 | -1,808,911 | -34,925,897 | -454,036,661 |
