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 605,233,343, 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 | 605,233,343 | |
| -1 | -605,233,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,233,343.
Example:
1 x 605,233,343 = 605,233,343
and
-1 x -605,233,343 = 605,233,343
Notice both answers equal 605,233,343
With that explanation out of the way, let's continue. Next, we take the number 605,233,343 and divide it by 2:
605,233,343 ÷ 2 = 302,616,671.5
If the quotient is a whole number, then 2 and 302,616,671.5 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 | 605,233,343 | |
| -1 | -605,233,343 |
Now, we try dividing 605,233,343 by 3:
605,233,343 ÷ 3 = 201,744,447.6667
If the quotient is a whole number, then 3 and 201,744,447.6667 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 | 605,233,343 | |
| -1 | -605,233,343 |
Let's try dividing by 4:
605,233,343 ÷ 4 = 151,308,335.75
If the quotient is a whole number, then 4 and 151,308,335.75 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 | 605,233,343 | |
| -1 | 605,233,343 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 97 | 143 | 1,067 | 1,261 | 13,871 | 43,633 | 479,963 | 567,229 | 4,232,401 | 6,239,519 | 46,556,411 | 55,021,213 | 605,233,343 |
| -1 | -11 | -13 | -97 | -143 | -1,067 | -1,261 | -13,871 | -43,633 | -479,963 | -567,229 | -4,232,401 | -6,239,519 | -46,556,411 | -55,021,213 | -605,233,343 |
