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 232,450,153, 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 | 232,450,153 | |
| -1 | -232,450,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,450,153.
Example:
1 x 232,450,153 = 232,450,153
and
-1 x -232,450,153 = 232,450,153
Notice both answers equal 232,450,153
With that explanation out of the way, let's continue. Next, we take the number 232,450,153 and divide it by 2:
232,450,153 ÷ 2 = 116,225,076.5
If the quotient is a whole number, then 2 and 116,225,076.5 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 | 232,450,153 | |
| -1 | -232,450,153 |
Now, we try dividing 232,450,153 by 3:
232,450,153 ÷ 3 = 77,483,384.3333
If the quotient is a whole number, then 3 and 77,483,384.3333 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 | 232,450,153 | |
| -1 | -232,450,153 |
Let's try dividing by 4:
232,450,153 ÷ 4 = 58,112,538.25
If the quotient is a whole number, then 4 and 58,112,538.25 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 | 232,450,153 | |
| -1 | 232,450,153 |
If you did it right, you will end up with this table:
| 1 | 13 | 79 | 113 | 1,027 | 1,469 | 2,003 | 8,927 | 26,039 | 116,051 | 158,237 | 226,339 | 2,057,081 | 2,942,407 | 17,880,781 | 232,450,153 |
| -1 | -13 | -79 | -113 | -1,027 | -1,469 | -2,003 | -8,927 | -26,039 | -116,051 | -158,237 | -226,339 | -2,057,081 | -2,942,407 | -17,880,781 | -232,450,153 |
