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 132,025,213, 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 | 132,025,213 | |
| -1 | -132,025,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,025,213.
Example:
1 x 132,025,213 = 132,025,213
and
-1 x -132,025,213 = 132,025,213
Notice both answers equal 132,025,213
With that explanation out of the way, let's continue. Next, we take the number 132,025,213 and divide it by 2:
132,025,213 ÷ 2 = 66,012,606.5
If the quotient is a whole number, then 2 and 66,012,606.5 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 | 132,025,213 | |
| -1 | -132,025,213 |
Now, we try dividing 132,025,213 by 3:
132,025,213 ÷ 3 = 44,008,404.3333
If the quotient is a whole number, then 3 and 44,008,404.3333 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 | 132,025,213 | |
| -1 | -132,025,213 |
Let's try dividing by 4:
132,025,213 ÷ 4 = 33,006,303.25
If the quotient is a whole number, then 4 and 33,006,303.25 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 | 132,025,213 | |
| -1 | 132,025,213 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 431 | 487 | 629 | 7,327 | 8,279 | 15,947 | 18,019 | 209,897 | 271,099 | 306,323 | 3,568,249 | 7,766,189 | 132,025,213 |
| -1 | -17 | -37 | -431 | -487 | -629 | -7,327 | -8,279 | -15,947 | -18,019 | -209,897 | -271,099 | -306,323 | -3,568,249 | -7,766,189 | -132,025,213 |
