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 130,033,145, 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 | 130,033,145 | |
| -1 | -130,033,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,033,145.
Example:
1 x 130,033,145 = 130,033,145
and
-1 x -130,033,145 = 130,033,145
Notice both answers equal 130,033,145
With that explanation out of the way, let's continue. Next, we take the number 130,033,145 and divide it by 2:
130,033,145 ÷ 2 = 65,016,572.5
If the quotient is a whole number, then 2 and 65,016,572.5 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 | 130,033,145 | |
| -1 | -130,033,145 |
Now, we try dividing 130,033,145 by 3:
130,033,145 ÷ 3 = 43,344,381.6667
If the quotient is a whole number, then 3 and 43,344,381.6667 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 | 130,033,145 | |
| -1 | -130,033,145 |
Let's try dividing by 4:
130,033,145 ÷ 4 = 32,508,286.25
If the quotient is a whole number, then 4 and 32,508,286.25 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 | 130,033,145 | |
| -1 | 130,033,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 102,793 | 513,965 | 1,130,723 | 2,364,239 | 5,653,615 | 11,821,195 | 26,006,629 | 130,033,145 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -102,793 | -513,965 | -1,130,723 | -2,364,239 | -5,653,615 | -11,821,195 | -26,006,629 | -130,033,145 |
