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 437,225,665, 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 | 437,225,665 | |
| -1 | -437,225,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 437,225,665.
Example:
1 x 437,225,665 = 437,225,665
and
-1 x -437,225,665 = 437,225,665
Notice both answers equal 437,225,665
With that explanation out of the way, let's continue. Next, we take the number 437,225,665 and divide it by 2:
437,225,665 ÷ 2 = 218,612,832.5
If the quotient is a whole number, then 2 and 218,612,832.5 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 | 437,225,665 | |
| -1 | -437,225,665 |
Now, we try dividing 437,225,665 by 3:
437,225,665 ÷ 3 = 145,741,888.3333
If the quotient is a whole number, then 3 and 145,741,888.3333 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 | 437,225,665 | |
| -1 | -437,225,665 |
Let's try dividing by 4:
437,225,665 ÷ 4 = 109,306,416.25
If the quotient is a whole number, then 4 and 109,306,416.25 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 | 437,225,665 | |
| -1 | 437,225,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 233 | 263 | 1,165 | 1,315 | 1,427 | 7,135 | 61,279 | 306,395 | 332,491 | 375,301 | 1,662,455 | 1,876,505 | 87,445,133 | 437,225,665 |
| -1 | -5 | -233 | -263 | -1,165 | -1,315 | -1,427 | -7,135 | -61,279 | -306,395 | -332,491 | -375,301 | -1,662,455 | -1,876,505 | -87,445,133 | -437,225,665 |
