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 132,031,523, 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 | 132,031,523 | |
| -1 | -132,031,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,031,523.
Example:
1 x 132,031,523 = 132,031,523
and
-1 x -132,031,523 = 132,031,523
Notice both answers equal 132,031,523
With that explanation out of the way, let's continue. Next, we take the number 132,031,523 and divide it by 2:
132,031,523 ÷ 2 = 66,015,761.5
If the quotient is a whole number, then 2 and 66,015,761.5 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 | 132,031,523 | |
| -1 | -132,031,523 |
Now, we try dividing 132,031,523 by 3:
132,031,523 ÷ 3 = 44,010,507.6667
If the quotient is a whole number, then 3 and 44,010,507.6667 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 | 132,031,523 | |
| -1 | -132,031,523 |
Let's try dividing by 4:
132,031,523 ÷ 4 = 33,007,880.75
If the quotient is a whole number, then 4 and 33,007,880.75 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 | 132,031,523 | |
| -1 | 132,031,523 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 73 | 263 | 299 | 529 | 949 | 1,679 | 3,419 | 6,049 | 6,877 | 19,199 | 21,827 | 38,617 | 78,637 | 139,127 | 249,587 | 441,577 | 502,021 | 1,808,651 | 5,740,501 | 10,156,271 | 132,031,523 |
| -1 | -13 | -23 | -73 | -263 | -299 | -529 | -949 | -1,679 | -3,419 | -6,049 | -6,877 | -19,199 | -21,827 | -38,617 | -78,637 | -139,127 | -249,587 | -441,577 | -502,021 | -1,808,651 | -5,740,501 | -10,156,271 | -132,031,523 |
