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 130,303,033, 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 | 130,303,033 | |
| -1 | -130,303,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,303,033.
Example:
1 x 130,303,033 = 130,303,033
and
-1 x -130,303,033 = 130,303,033
Notice both answers equal 130,303,033
With that explanation out of the way, let's continue. Next, we take the number 130,303,033 and divide it by 2:
130,303,033 ÷ 2 = 65,151,516.5
If the quotient is a whole number, then 2 and 65,151,516.5 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 | 130,303,033 | |
| -1 | -130,303,033 |
Now, we try dividing 130,303,033 by 3:
130,303,033 ÷ 3 = 43,434,344.3333
If the quotient is a whole number, then 3 and 43,434,344.3333 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 | 130,303,033 | |
| -1 | -130,303,033 |
Let's try dividing by 4:
130,303,033 ÷ 4 = 32,575,758.25
If the quotient is a whole number, then 4 and 32,575,758.25 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 | 130,303,033 | |
| -1 | 130,303,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 149 | 271 | 461 | 1,043 | 1,897 | 3,227 | 40,379 | 68,689 | 124,931 | 282,653 | 480,823 | 874,517 | 18,614,719 | 130,303,033 |
| -1 | -7 | -149 | -271 | -461 | -1,043 | -1,897 | -3,227 | -40,379 | -68,689 | -124,931 | -282,653 | -480,823 | -874,517 | -18,614,719 | -130,303,033 |
