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 132,551,431, 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 | 132,551,431 | |
| -1 | -132,551,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,551,431.
Example:
1 x 132,551,431 = 132,551,431
and
-1 x -132,551,431 = 132,551,431
Notice both answers equal 132,551,431
With that explanation out of the way, let's continue. Next, we take the number 132,551,431 and divide it by 2:
132,551,431 ÷ 2 = 66,275,715.5
If the quotient is a whole number, then 2 and 66,275,715.5 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 | 132,551,431 | |
| -1 | -132,551,431 |
Now, we try dividing 132,551,431 by 3:
132,551,431 ÷ 3 = 44,183,810.3333
If the quotient is a whole number, then 3 and 44,183,810.3333 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 | 132,551,431 | |
| -1 | -132,551,431 |
Let's try dividing by 4:
132,551,431 ÷ 4 = 33,137,857.75
If the quotient is a whole number, then 4 and 33,137,857.75 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 | 132,551,431 | |
| -1 | 132,551,431 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 313 | 493 | 859 | 5,321 | 9,077 | 14,603 | 24,911 | 154,309 | 268,867 | 423,487 | 4,570,739 | 7,797,143 | 132,551,431 |
| -1 | -17 | -29 | -313 | -493 | -859 | -5,321 | -9,077 | -14,603 | -24,911 | -154,309 | -268,867 | -423,487 | -4,570,739 | -7,797,143 | -132,551,431 |
