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 132,215,549, 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 | 132,215,549 | |
| -1 | -132,215,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,215,549.
Example:
1 x 132,215,549 = 132,215,549
and
-1 x -132,215,549 = 132,215,549
Notice both answers equal 132,215,549
With that explanation out of the way, let's continue. Next, we take the number 132,215,549 and divide it by 2:
132,215,549 ÷ 2 = 66,107,774.5
If the quotient is a whole number, then 2 and 66,107,774.5 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 | 132,215,549 | |
| -1 | -132,215,549 |
Now, we try dividing 132,215,549 by 3:
132,215,549 ÷ 3 = 44,071,849.6667
If the quotient is a whole number, then 3 and 44,071,849.6667 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 | 132,215,549 | |
| -1 | -132,215,549 |
Let's try dividing by 4:
132,215,549 ÷ 4 = 33,053,887.25
If the quotient is a whole number, then 4 and 33,053,887.25 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 | 132,215,549 | |
| -1 | 132,215,549 |
If you did it right, you will end up with this table:
| 1 | 53 | 131 | 137 | 139 | 6,943 | 7,261 | 7,367 | 17,947 | 18,209 | 19,043 | 951,191 | 965,077 | 1,009,279 | 2,494,633 | 132,215,549 |
| -1 | -53 | -131 | -137 | -139 | -6,943 | -7,261 | -7,367 | -17,947 | -18,209 | -19,043 | -951,191 | -965,077 | -1,009,279 | -2,494,633 | -132,215,549 |
