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 602,231,239, 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 | 602,231,239 | |
| -1 | -602,231,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 602,231,239.
Example:
1 x 602,231,239 = 602,231,239
and
-1 x -602,231,239 = 602,231,239
Notice both answers equal 602,231,239
With that explanation out of the way, let's continue. Next, we take the number 602,231,239 and divide it by 2:
602,231,239 ÷ 2 = 301,115,619.5
If the quotient is a whole number, then 2 and 301,115,619.5 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 | 602,231,239 | |
| -1 | -602,231,239 |
Now, we try dividing 602,231,239 by 3:
602,231,239 ÷ 3 = 200,743,746.3333
If the quotient is a whole number, then 3 and 200,743,746.3333 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 | 602,231,239 | |
| -1 | -602,231,239 |
Let's try dividing by 4:
602,231,239 ÷ 4 = 150,557,809.75
If the quotient is a whole number, then 4 and 150,557,809.75 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 | 602,231,239 | |
| -1 | 602,231,239 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 73 | 323 | 1,241 | 1,387 | 23,579 | 25,541 | 434,197 | 485,279 | 1,864,493 | 8,249,743 | 31,696,381 | 35,425,367 | 602,231,239 |
| -1 | -17 | -19 | -73 | -323 | -1,241 | -1,387 | -23,579 | -25,541 | -434,197 | -485,279 | -1,864,493 | -8,249,743 | -31,696,381 | -35,425,367 | -602,231,239 |
