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 132,945,299, 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 | 132,945,299 | |
| -1 | -132,945,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,945,299.
Example:
1 x 132,945,299 = 132,945,299
and
-1 x -132,945,299 = 132,945,299
Notice both answers equal 132,945,299
With that explanation out of the way, let's continue. Next, we take the number 132,945,299 and divide it by 2:
132,945,299 ÷ 2 = 66,472,649.5
If the quotient is a whole number, then 2 and 66,472,649.5 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 | 132,945,299 | |
| -1 | -132,945,299 |
Now, we try dividing 132,945,299 by 3:
132,945,299 ÷ 3 = 44,315,099.6667
If the quotient is a whole number, then 3 and 44,315,099.6667 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 | 132,945,299 | |
| -1 | -132,945,299 |
Let's try dividing by 4:
132,945,299 ÷ 4 = 33,236,324.75
If the quotient is a whole number, then 4 and 33,236,324.75 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 | 132,945,299 | |
| -1 | 132,945,299 |
If you did it right, you will end up with this table:
| 1 | 19 | 71 | 139 | 709 | 1,349 | 2,641 | 9,869 | 13,471 | 50,339 | 98,551 | 187,511 | 956,441 | 1,872,469 | 6,997,121 | 132,945,299 |
| -1 | -19 | -71 | -139 | -709 | -1,349 | -2,641 | -9,869 | -13,471 | -50,339 | -98,551 | -187,511 | -956,441 | -1,872,469 | -6,997,121 | -132,945,299 |
