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 132,635,143, 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 | 132,635,143 | |
| -1 | -132,635,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,635,143.
Example:
1 x 132,635,143 = 132,635,143
and
-1 x -132,635,143 = 132,635,143
Notice both answers equal 132,635,143
With that explanation out of the way, let's continue. Next, we take the number 132,635,143 and divide it by 2:
132,635,143 ÷ 2 = 66,317,571.5
If the quotient is a whole number, then 2 and 66,317,571.5 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 | 132,635,143 | |
| -1 | -132,635,143 |
Now, we try dividing 132,635,143 by 3:
132,635,143 ÷ 3 = 44,211,714.3333
If the quotient is a whole number, then 3 and 44,211,714.3333 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 | 132,635,143 | |
| -1 | -132,635,143 |
Let's try dividing by 4:
132,635,143 ÷ 4 = 33,158,785.75
If the quotient is a whole number, then 4 and 33,158,785.75 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 | 132,635,143 | |
| -1 | 132,635,143 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 67 | 589 | 1,273 | 2,077 | 3,361 | 39,463 | 63,859 | 104,191 | 225,187 | 1,979,629 | 4,278,553 | 6,980,797 | 132,635,143 |
| -1 | -19 | -31 | -67 | -589 | -1,273 | -2,077 | -3,361 | -39,463 | -63,859 | -104,191 | -225,187 | -1,979,629 | -4,278,553 | -6,980,797 | -132,635,143 |
