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 454,156,231, 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 | 454,156,231 | |
| -1 | -454,156,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 454,156,231.
Example:
1 x 454,156,231 = 454,156,231
and
-1 x -454,156,231 = 454,156,231
Notice both answers equal 454,156,231
With that explanation out of the way, let's continue. Next, we take the number 454,156,231 and divide it by 2:
454,156,231 ÷ 2 = 227,078,115.5
If the quotient is a whole number, then 2 and 227,078,115.5 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 | 454,156,231 | |
| -1 | -454,156,231 |
Now, we try dividing 454,156,231 by 3:
454,156,231 ÷ 3 = 151,385,410.3333
If the quotient is a whole number, then 3 and 151,385,410.3333 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 | 454,156,231 | |
| -1 | -454,156,231 |
Let's try dividing by 4:
454,156,231 ÷ 4 = 113,539,057.75
If the quotient is a whole number, then 4 and 113,539,057.75 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 | 454,156,231 | |
| -1 | 454,156,231 |
If you did it right, you will end up with this table:
| 1 | 31 | 89 | 97 | 1,697 | 2,759 | 3,007 | 8,633 | 52,607 | 151,033 | 164,609 | 267,623 | 4,682,023 | 5,102,879 | 14,650,201 | 454,156,231 |
| -1 | -31 | -89 | -97 | -1,697 | -2,759 | -3,007 | -8,633 | -52,607 | -151,033 | -164,609 | -267,623 | -4,682,023 | -5,102,879 | -14,650,201 | -454,156,231 |
