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 130,642,535, 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 | 130,642,535 | |
| -1 | -130,642,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,642,535.
Example:
1 x 130,642,535 = 130,642,535
and
-1 x -130,642,535 = 130,642,535
Notice both answers equal 130,642,535
With that explanation out of the way, let's continue. Next, we take the number 130,642,535 and divide it by 2:
130,642,535 ÷ 2 = 65,321,267.5
If the quotient is a whole number, then 2 and 65,321,267.5 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 | 130,642,535 | |
| -1 | -130,642,535 |
Now, we try dividing 130,642,535 by 3:
130,642,535 ÷ 3 = 43,547,511.6667
If the quotient is a whole number, then 3 and 43,547,511.6667 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 | 130,642,535 | |
| -1 | -130,642,535 |
Let's try dividing by 4:
130,642,535 ÷ 4 = 32,660,633.75
If the quotient is a whole number, then 4 and 32,660,633.75 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 | 130,642,535 | |
| -1 | 130,642,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 52,999 | 264,995 | 900,983 | 1,536,971 | 4,504,915 | 7,684,855 | 26,128,507 | 130,642,535 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -52,999 | -264,995 | -900,983 | -1,536,971 | -4,504,915 | -7,684,855 | -26,128,507 | -130,642,535 |
