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 234,155,125, 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 | 234,155,125 | |
| -1 | -234,155,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,155,125.
Example:
1 x 234,155,125 = 234,155,125
and
-1 x -234,155,125 = 234,155,125
Notice both answers equal 234,155,125
With that explanation out of the way, let's continue. Next, we take the number 234,155,125 and divide it by 2:
234,155,125 ÷ 2 = 117,077,562.5
If the quotient is a whole number, then 2 and 117,077,562.5 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 | 234,155,125 | |
| -1 | -234,155,125 |
Now, we try dividing 234,155,125 by 3:
234,155,125 ÷ 3 = 78,051,708.3333
If the quotient is a whole number, then 3 and 78,051,708.3333 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 | 234,155,125 | |
| -1 | -234,155,125 |
Let's try dividing by 4:
234,155,125 ÷ 4 = 58,538,781.25
If the quotient is a whole number, then 4 and 58,538,781.25 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 | 234,155,125 | |
| -1 | 234,155,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 1,291 | 1,451 | 6,455 | 7,255 | 32,275 | 36,275 | 161,375 | 181,375 | 1,873,241 | 9,366,205 | 46,831,025 | 234,155,125 |
| -1 | -5 | -25 | -125 | -1,291 | -1,451 | -6,455 | -7,255 | -32,275 | -36,275 | -161,375 | -181,375 | -1,873,241 | -9,366,205 | -46,831,025 | -234,155,125 |
