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 130,311,355, 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 | 130,311,355 | |
| -1 | -130,311,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,311,355.
Example:
1 x 130,311,355 = 130,311,355
and
-1 x -130,311,355 = 130,311,355
Notice both answers equal 130,311,355
With that explanation out of the way, let's continue. Next, we take the number 130,311,355 and divide it by 2:
130,311,355 ÷ 2 = 65,155,677.5
If the quotient is a whole number, then 2 and 65,155,677.5 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 | 130,311,355 | |
| -1 | -130,311,355 |
Now, we try dividing 130,311,355 by 3:
130,311,355 ÷ 3 = 43,437,118.3333
If the quotient is a whole number, then 3 and 43,437,118.3333 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 | 130,311,355 | |
| -1 | -130,311,355 |
Let's try dividing by 4:
130,311,355 ÷ 4 = 32,577,838.75
If the quotient is a whole number, then 4 and 32,577,838.75 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 | 130,311,355 | |
| -1 | 130,311,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 499 | 1,801 | 2,495 | 9,005 | 14,471 | 52,229 | 72,355 | 261,145 | 898,699 | 4,493,495 | 26,062,271 | 130,311,355 |
| -1 | -5 | -29 | -145 | -499 | -1,801 | -2,495 | -9,005 | -14,471 | -52,229 | -72,355 | -261,145 | -898,699 | -4,493,495 | -26,062,271 | -130,311,355 |
