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 132,572,245, 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 | 132,572,245 | |
| -1 | -132,572,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,572,245.
Example:
1 x 132,572,245 = 132,572,245
and
-1 x -132,572,245 = 132,572,245
Notice both answers equal 132,572,245
With that explanation out of the way, let's continue. Next, we take the number 132,572,245 and divide it by 2:
132,572,245 ÷ 2 = 66,286,122.5
If the quotient is a whole number, then 2 and 66,286,122.5 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 | 132,572,245 | |
| -1 | -132,572,245 |
Now, we try dividing 132,572,245 by 3:
132,572,245 ÷ 3 = 44,190,748.3333
If the quotient is a whole number, then 3 and 44,190,748.3333 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 | 132,572,245 | |
| -1 | -132,572,245 |
Let's try dividing by 4:
132,572,245 ÷ 4 = 33,143,061.25
If the quotient is a whole number, then 4 and 33,143,061.25 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 | 132,572,245 | |
| -1 | 132,572,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 293 | 1,465 | 3,809 | 6,961 | 19,045 | 34,805 | 90,493 | 452,465 | 2,039,573 | 10,197,865 | 26,514,449 | 132,572,245 |
| -1 | -5 | -13 | -65 | -293 | -1,465 | -3,809 | -6,961 | -19,045 | -34,805 | -90,493 | -452,465 | -2,039,573 | -10,197,865 | -26,514,449 | -132,572,245 |
