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 132,140,443, 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 | 132,140,443 | |
| -1 | -132,140,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,140,443.
Example:
1 x 132,140,443 = 132,140,443
and
-1 x -132,140,443 = 132,140,443
Notice both answers equal 132,140,443
With that explanation out of the way, let's continue. Next, we take the number 132,140,443 and divide it by 2:
132,140,443 ÷ 2 = 66,070,221.5
If the quotient is a whole number, then 2 and 66,070,221.5 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 | 132,140,443 | |
| -1 | -132,140,443 |
Now, we try dividing 132,140,443 by 3:
132,140,443 ÷ 3 = 44,046,814.3333
If the quotient is a whole number, then 3 and 44,046,814.3333 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 | 132,140,443 | |
| -1 | -132,140,443 |
Let's try dividing by 4:
132,140,443 ÷ 4 = 33,035,110.75
If the quotient is a whole number, then 4 and 33,035,110.75 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 | 132,140,443 | |
| -1 | 132,140,443 |
If you did it right, you will end up with this table:
| 1 | 29 | 71 | 841 | 2,059 | 2,213 | 59,711 | 64,177 | 157,123 | 1,861,133 | 4,556,567 | 132,140,443 |
| -1 | -29 | -71 | -841 | -2,059 | -2,213 | -59,711 | -64,177 | -157,123 | -1,861,133 | -4,556,567 | -132,140,443 |
