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 434,454,449, 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 | 434,454,449 | |
| -1 | -434,454,449 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 434,454,449.
Example:
1 x 434,454,449 = 434,454,449
and
-1 x -434,454,449 = 434,454,449
Notice both answers equal 434,454,449
With that explanation out of the way, let's continue. Next, we take the number 434,454,449 and divide it by 2:
434,454,449 ÷ 2 = 217,227,224.5
If the quotient is a whole number, then 2 and 217,227,224.5 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 | 434,454,449 | |
| -1 | -434,454,449 |
Now, we try dividing 434,454,449 by 3:
434,454,449 ÷ 3 = 144,818,149.6667
If the quotient is a whole number, then 3 and 144,818,149.6667 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 | 434,454,449 | |
| -1 | -434,454,449 |
Let's try dividing by 4:
434,454,449 ÷ 4 = 108,613,612.25
If the quotient is a whole number, then 4 and 108,613,612.25 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 | 434,454,449 | |
| -1 | 434,454,449 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 229 | 2,519 | 2,977 | 13,267 | 32,747 | 145,937 | 172,471 | 1,897,181 | 3,038,143 | 33,419,573 | 39,495,859 | 434,454,449 |
| -1 | -11 | -13 | -143 | -229 | -2,519 | -2,977 | -13,267 | -32,747 | -145,937 | -172,471 | -1,897,181 | -3,038,143 | -33,419,573 | -39,495,859 | -434,454,449 |
