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 130,404,635, 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 | 130,404,635 | |
| -1 | -130,404,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,404,635.
Example:
1 x 130,404,635 = 130,404,635
and
-1 x -130,404,635 = 130,404,635
Notice both answers equal 130,404,635
With that explanation out of the way, let's continue. Next, we take the number 130,404,635 and divide it by 2:
130,404,635 ÷ 2 = 65,202,317.5
If the quotient is a whole number, then 2 and 65,202,317.5 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 | 130,404,635 | |
| -1 | -130,404,635 |
Now, we try dividing 130,404,635 by 3:
130,404,635 ÷ 3 = 43,468,211.6667
If the quotient is a whole number, then 3 and 43,468,211.6667 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 | 130,404,635 | |
| -1 | -130,404,635 |
Let's try dividing by 4:
130,404,635 ÷ 4 = 32,601,158.75
If the quotient is a whole number, then 4 and 32,601,158.75 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 | 130,404,635 | |
| -1 | 130,404,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 101 | 355 | 505 | 3,637 | 7,171 | 18,185 | 35,855 | 258,227 | 367,337 | 1,291,135 | 1,836,685 | 26,080,927 | 130,404,635 |
| -1 | -5 | -71 | -101 | -355 | -505 | -3,637 | -7,171 | -18,185 | -35,855 | -258,227 | -367,337 | -1,291,135 | -1,836,685 | -26,080,927 | -130,404,635 |
