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 132,744,605, 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 | 132,744,605 | |
| -1 | -132,744,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,744,605.
Example:
1 x 132,744,605 = 132,744,605
and
-1 x -132,744,605 = 132,744,605
Notice both answers equal 132,744,605
With that explanation out of the way, let's continue. Next, we take the number 132,744,605 and divide it by 2:
132,744,605 ÷ 2 = 66,372,302.5
If the quotient is a whole number, then 2 and 66,372,302.5 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 | 132,744,605 | |
| -1 | -132,744,605 |
Now, we try dividing 132,744,605 by 3:
132,744,605 ÷ 3 = 44,248,201.6667
If the quotient is a whole number, then 3 and 44,248,201.6667 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 | 132,744,605 | |
| -1 | -132,744,605 |
Let's try dividing by 4:
132,744,605 ÷ 4 = 33,186,151.25
If the quotient is a whole number, then 4 and 33,186,151.25 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 | 132,744,605 | |
| -1 | 132,744,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 449 | 2,245 | 3,143 | 8,447 | 15,715 | 42,235 | 59,129 | 295,645 | 3,792,703 | 18,963,515 | 26,548,921 | 132,744,605 |
| -1 | -5 | -7 | -35 | -449 | -2,245 | -3,143 | -8,447 | -15,715 | -42,235 | -59,129 | -295,645 | -3,792,703 | -18,963,515 | -26,548,921 | -132,744,605 |
