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 132,238,529, 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 | 132,238,529 | |
| -1 | -132,238,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,238,529.
Example:
1 x 132,238,529 = 132,238,529
and
-1 x -132,238,529 = 132,238,529
Notice both answers equal 132,238,529
With that explanation out of the way, let's continue. Next, we take the number 132,238,529 and divide it by 2:
132,238,529 ÷ 2 = 66,119,264.5
If the quotient is a whole number, then 2 and 66,119,264.5 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 | 132,238,529 | |
| -1 | -132,238,529 |
Now, we try dividing 132,238,529 by 3:
132,238,529 ÷ 3 = 44,079,509.6667
If the quotient is a whole number, then 3 and 44,079,509.6667 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 | 132,238,529 | |
| -1 | -132,238,529 |
Let's try dividing by 4:
132,238,529 ÷ 4 = 33,059,632.25
If the quotient is a whole number, then 4 and 33,059,632.25 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 | 132,238,529 | |
| -1 | 132,238,529 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 59 | 527 | 1,003 | 1,829 | 4,253 | 31,093 | 72,301 | 131,843 | 250,927 | 2,241,331 | 4,265,759 | 7,778,737 | 132,238,529 |
| -1 | -17 | -31 | -59 | -527 | -1,003 | -1,829 | -4,253 | -31,093 | -72,301 | -131,843 | -250,927 | -2,241,331 | -4,265,759 | -7,778,737 | -132,238,529 |
