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 132,788,275, 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 | 132,788,275 | |
| -1 | -132,788,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,788,275.
Example:
1 x 132,788,275 = 132,788,275
and
-1 x -132,788,275 = 132,788,275
Notice both answers equal 132,788,275
With that explanation out of the way, let's continue. Next, we take the number 132,788,275 and divide it by 2:
132,788,275 ÷ 2 = 66,394,137.5
If the quotient is a whole number, then 2 and 66,394,137.5 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 | 132,788,275 | |
| -1 | -132,788,275 |
Now, we try dividing 132,788,275 by 3:
132,788,275 ÷ 3 = 44,262,758.3333
If the quotient is a whole number, then 3 and 44,262,758.3333 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 | 132,788,275 | |
| -1 | -132,788,275 |
Let's try dividing by 4:
132,788,275 ÷ 4 = 33,197,068.75
If the quotient is a whole number, then 4 and 33,197,068.75 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 | 132,788,275 | |
| -1 | 132,788,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 289 | 425 | 1,445 | 7,225 | 18,379 | 91,895 | 312,443 | 459,475 | 1,562,215 | 5,311,531 | 7,811,075 | 26,557,655 | 132,788,275 |
| -1 | -5 | -17 | -25 | -85 | -289 | -425 | -1,445 | -7,225 | -18,379 | -91,895 | -312,443 | -459,475 | -1,562,215 | -5,311,531 | -7,811,075 | -26,557,655 | -132,788,275 |
