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 232,102,745, 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 | 232,102,745 | |
| -1 | -232,102,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,102,745.
Example:
1 x 232,102,745 = 232,102,745
and
-1 x -232,102,745 = 232,102,745
Notice both answers equal 232,102,745
With that explanation out of the way, let's continue. Next, we take the number 232,102,745 and divide it by 2:
232,102,745 ÷ 2 = 116,051,372.5
If the quotient is a whole number, then 2 and 116,051,372.5 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 | 232,102,745 | |
| -1 | -232,102,745 |
Now, we try dividing 232,102,745 by 3:
232,102,745 ÷ 3 = 77,367,581.6667
If the quotient is a whole number, then 3 and 77,367,581.6667 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 | 232,102,745 | |
| -1 | -232,102,745 |
Let's try dividing by 4:
232,102,745 ÷ 4 = 58,025,686.25
If the quotient is a whole number, then 4 and 58,025,686.25 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 | 232,102,745 | |
| -1 | 232,102,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 307 | 1,535 | 2,149 | 10,745 | 21,601 | 108,005 | 151,207 | 756,035 | 6,631,507 | 33,157,535 | 46,420,549 | 232,102,745 |
| -1 | -5 | -7 | -35 | -307 | -1,535 | -2,149 | -10,745 | -21,601 | -108,005 | -151,207 | -756,035 | -6,631,507 | -33,157,535 | -46,420,549 | -232,102,745 |
