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 132,321,415, 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 | 132,321,415 | |
| -1 | -132,321,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,321,415.
Example:
1 x 132,321,415 = 132,321,415
and
-1 x -132,321,415 = 132,321,415
Notice both answers equal 132,321,415
With that explanation out of the way, let's continue. Next, we take the number 132,321,415 and divide it by 2:
132,321,415 ÷ 2 = 66,160,707.5
If the quotient is a whole number, then 2 and 66,160,707.5 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 | 132,321,415 | |
| -1 | -132,321,415 |
Now, we try dividing 132,321,415 by 3:
132,321,415 ÷ 3 = 44,107,138.3333
If the quotient is a whole number, then 3 and 44,107,138.3333 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 | 132,321,415 | |
| -1 | -132,321,415 |
Let's try dividing by 4:
132,321,415 ÷ 4 = 33,080,353.75
If the quotient is a whole number, then 4 and 33,080,353.75 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 | 132,321,415 | |
| -1 | 132,321,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 529 | 2,185 | 2,633 | 2,645 | 10,051 | 13,165 | 50,027 | 50,255 | 60,559 | 250,135 | 302,795 | 1,150,621 | 1,392,857 | 5,753,105 | 6,964,285 | 26,464,283 | 132,321,415 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -529 | -2,185 | -2,633 | -2,645 | -10,051 | -13,165 | -50,027 | -50,255 | -60,559 | -250,135 | -302,795 | -1,150,621 | -1,392,857 | -5,753,105 | -6,964,285 | -26,464,283 | -132,321,415 |
