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 303,440,423, 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 | 303,440,423 | |
| -1 | -303,440,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,440,423.
Example:
1 x 303,440,423 = 303,440,423
and
-1 x -303,440,423 = 303,440,423
Notice both answers equal 303,440,423
With that explanation out of the way, let's continue. Next, we take the number 303,440,423 and divide it by 2:
303,440,423 ÷ 2 = 151,720,211.5
If the quotient is a whole number, then 2 and 151,720,211.5 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 | 303,440,423 | |
| -1 | -303,440,423 |
Now, we try dividing 303,440,423 by 3:
303,440,423 ÷ 3 = 101,146,807.6667
If the quotient is a whole number, then 3 and 101,146,807.6667 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 | 303,440,423 | |
| -1 | -303,440,423 |
Let's try dividing by 4:
303,440,423 ÷ 4 = 75,860,105.75
If the quotient is a whole number, then 4 and 75,860,105.75 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 | 303,440,423 | |
| -1 | 303,440,423 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 53 | 143 | 583 | 689 | 7,579 | 40,037 | 440,407 | 520,481 | 2,121,961 | 5,725,291 | 23,341,571 | 27,585,493 | 303,440,423 |
| -1 | -11 | -13 | -53 | -143 | -583 | -689 | -7,579 | -40,037 | -440,407 | -520,481 | -2,121,961 | -5,725,291 | -23,341,571 | -27,585,493 | -303,440,423 |
