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 443,002,231, 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 | 443,002,231 | |
| -1 | -443,002,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 443,002,231.
Example:
1 x 443,002,231 = 443,002,231
and
-1 x -443,002,231 = 443,002,231
Notice both answers equal 443,002,231
With that explanation out of the way, let's continue. Next, we take the number 443,002,231 and divide it by 2:
443,002,231 ÷ 2 = 221,501,115.5
If the quotient is a whole number, then 2 and 221,501,115.5 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 | 443,002,231 | |
| -1 | -443,002,231 |
Now, we try dividing 443,002,231 by 3:
443,002,231 ÷ 3 = 147,667,410.3333
If the quotient is a whole number, then 3 and 147,667,410.3333 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 | 443,002,231 | |
| -1 | -443,002,231 |
Let's try dividing by 4:
443,002,231 ÷ 4 = 110,750,557.75
If the quotient is a whole number, then 4 and 110,750,557.75 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 | 443,002,231 | |
| -1 | 443,002,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 1,289 | 1,693 | 9,023 | 11,851 | 37,381 | 49,097 | 261,667 | 343,679 | 2,182,277 | 15,275,939 | 63,286,033 | 443,002,231 |
| -1 | -7 | -29 | -203 | -1,289 | -1,693 | -9,023 | -11,851 | -37,381 | -49,097 | -261,667 | -343,679 | -2,182,277 | -15,275,939 | -63,286,033 | -443,002,231 |
