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 132,238,535, 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 | 132,238,535 | |
| -1 | -132,238,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,238,535.
Example:
1 x 132,238,535 = 132,238,535
and
-1 x -132,238,535 = 132,238,535
Notice both answers equal 132,238,535
With that explanation out of the way, let's continue. Next, we take the number 132,238,535 and divide it by 2:
132,238,535 ÷ 2 = 66,119,267.5
If the quotient is a whole number, then 2 and 66,119,267.5 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 | 132,238,535 | |
| -1 | -132,238,535 |
Now, we try dividing 132,238,535 by 3:
132,238,535 ÷ 3 = 44,079,511.6667
If the quotient is a whole number, then 3 and 44,079,511.6667 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 | 132,238,535 | |
| -1 | -132,238,535 |
Let's try dividing by 4:
132,238,535 ÷ 4 = 33,059,633.75
If the quotient is a whole number, then 4 and 33,059,633.75 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 | 132,238,535 | |
| -1 | 132,238,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 184,949 | 924,745 | 2,034,439 | 2,404,337 | 10,172,195 | 12,021,685 | 26,447,707 | 132,238,535 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -184,949 | -924,745 | -2,034,439 | -2,404,337 | -10,172,195 | -12,021,685 | -26,447,707 | -132,238,535 |
