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 132,072,773, 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 | 132,072,773 | |
| -1 | -132,072,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,072,773.
Example:
1 x 132,072,773 = 132,072,773
and
-1 x -132,072,773 = 132,072,773
Notice both answers equal 132,072,773
With that explanation out of the way, let's continue. Next, we take the number 132,072,773 and divide it by 2:
132,072,773 ÷ 2 = 66,036,386.5
If the quotient is a whole number, then 2 and 66,036,386.5 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 | 132,072,773 | |
| -1 | -132,072,773 |
Now, we try dividing 132,072,773 by 3:
132,072,773 ÷ 3 = 44,024,257.6667
If the quotient is a whole number, then 3 and 44,024,257.6667 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 | 132,072,773 | |
| -1 | -132,072,773 |
Let's try dividing by 4:
132,072,773 ÷ 4 = 33,018,193.25
If the quotient is a whole number, then 4 and 33,018,193.25 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 | 132,072,773 | |
| -1 | 132,072,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 229 | 329 | 1,603 | 1,753 | 10,763 | 12,271 | 75,341 | 82,391 | 401,437 | 576,737 | 2,810,059 | 18,867,539 | 132,072,773 |
| -1 | -7 | -47 | -229 | -329 | -1,603 | -1,753 | -10,763 | -12,271 | -75,341 | -82,391 | -401,437 | -576,737 | -2,810,059 | -18,867,539 | -132,072,773 |
