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 132,254,773, 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 | 132,254,773 | |
| -1 | -132,254,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,254,773.
Example:
1 x 132,254,773 = 132,254,773
and
-1 x -132,254,773 = 132,254,773
Notice both answers equal 132,254,773
With that explanation out of the way, let's continue. Next, we take the number 132,254,773 and divide it by 2:
132,254,773 ÷ 2 = 66,127,386.5
If the quotient is a whole number, then 2 and 66,127,386.5 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 | 132,254,773 | |
| -1 | -132,254,773 |
Now, we try dividing 132,254,773 by 3:
132,254,773 ÷ 3 = 44,084,924.3333
If the quotient is a whole number, then 3 and 44,084,924.3333 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 | 132,254,773 | |
| -1 | -132,254,773 |
Let's try dividing by 4:
132,254,773 ÷ 4 = 33,063,693.25
If the quotient is a whole number, then 4 and 33,063,693.25 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 | 132,254,773 | |
| -1 | 132,254,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 83 | 217 | 581 | 1,049 | 1,519 | 2,573 | 4,067 | 7,343 | 18,011 | 32,519 | 51,401 | 87,067 | 126,077 | 227,633 | 609,469 | 1,593,431 | 2,699,077 | 4,266,283 | 18,893,539 | 132,254,773 |
| -1 | -7 | -31 | -49 | -83 | -217 | -581 | -1,049 | -1,519 | -2,573 | -4,067 | -7,343 | -18,011 | -32,519 | -51,401 | -87,067 | -126,077 | -227,633 | -609,469 | -1,593,431 | -2,699,077 | -4,266,283 | -18,893,539 | -132,254,773 |
