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 235,232,155, 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 | 235,232,155 | |
| -1 | -235,232,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,232,155.
Example:
1 x 235,232,155 = 235,232,155
and
-1 x -235,232,155 = 235,232,155
Notice both answers equal 235,232,155
With that explanation out of the way, let's continue. Next, we take the number 235,232,155 and divide it by 2:
235,232,155 ÷ 2 = 117,616,077.5
If the quotient is a whole number, then 2 and 117,616,077.5 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 | 235,232,155 | |
| -1 | -235,232,155 |
Now, we try dividing 235,232,155 by 3:
235,232,155 ÷ 3 = 78,410,718.3333
If the quotient is a whole number, then 3 and 78,410,718.3333 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 | 235,232,155 | |
| -1 | -235,232,155 |
Let's try dividing by 4:
235,232,155 ÷ 4 = 58,808,038.75
If the quotient is a whole number, then 4 and 58,808,038.75 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 | 235,232,155 | |
| -1 | 235,232,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 227 | 1,135 | 5,221 | 9,011 | 26,105 | 45,055 | 207,253 | 1,036,265 | 2,045,497 | 10,227,485 | 47,046,431 | 235,232,155 |
| -1 | -5 | -23 | -115 | -227 | -1,135 | -5,221 | -9,011 | -26,105 | -45,055 | -207,253 | -1,036,265 | -2,045,497 | -10,227,485 | -47,046,431 | -235,232,155 |
