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 437,253,515, 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 | 437,253,515 | |
| -1 | -437,253,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 437,253,515.
Example:
1 x 437,253,515 = 437,253,515
and
-1 x -437,253,515 = 437,253,515
Notice both answers equal 437,253,515
With that explanation out of the way, let's continue. Next, we take the number 437,253,515 and divide it by 2:
437,253,515 ÷ 2 = 218,626,757.5
If the quotient is a whole number, then 2 and 218,626,757.5 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 | 437,253,515 | |
| -1 | -437,253,515 |
Now, we try dividing 437,253,515 by 3:
437,253,515 ÷ 3 = 145,751,171.6667
If the quotient is a whole number, then 3 and 145,751,171.6667 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 | 437,253,515 | |
| -1 | -437,253,515 |
Let's try dividing by 4:
437,253,515 ÷ 4 = 109,313,378.75
If the quotient is a whole number, then 4 and 109,313,378.75 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 | 437,253,515 | |
| -1 | 437,253,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 881 | 4,405 | 5,839 | 14,977 | 29,195 | 74,885 | 99,263 | 496,315 | 5,144,159 | 25,720,795 | 87,450,703 | 437,253,515 |
| -1 | -5 | -17 | -85 | -881 | -4,405 | -5,839 | -14,977 | -29,195 | -74,885 | -99,263 | -496,315 | -5,144,159 | -25,720,795 | -87,450,703 | -437,253,515 |
