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 132,551,429, 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 | 132,551,429 | |
| -1 | -132,551,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,551,429.
Example:
1 x 132,551,429 = 132,551,429
and
-1 x -132,551,429 = 132,551,429
Notice both answers equal 132,551,429
With that explanation out of the way, let's continue. Next, we take the number 132,551,429 and divide it by 2:
132,551,429 ÷ 2 = 66,275,714.5
If the quotient is a whole number, then 2 and 66,275,714.5 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 | 132,551,429 | |
| -1 | -132,551,429 |
Now, we try dividing 132,551,429 by 3:
132,551,429 ÷ 3 = 44,183,809.6667
If the quotient is a whole number, then 3 and 44,183,809.6667 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 | 132,551,429 | |
| -1 | -132,551,429 |
Let's try dividing by 4:
132,551,429 ÷ 4 = 33,137,857.25
If the quotient is a whole number, then 4 and 33,137,857.25 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 | 132,551,429 | |
| -1 | 132,551,429 |
If you did it right, you will end up with this table:
| 1 | 19 | 73 | 227 | 421 | 1,387 | 4,313 | 7,999 | 16,571 | 30,733 | 95,567 | 314,849 | 583,927 | 1,815,773 | 6,976,391 | 132,551,429 |
| -1 | -19 | -73 | -227 | -421 | -1,387 | -4,313 | -7,999 | -16,571 | -30,733 | -95,567 | -314,849 | -583,927 | -1,815,773 | -6,976,391 | -132,551,429 |
