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 130,763,375, 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 | 130,763,375 | |
| -1 | -130,763,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,763,375.
Example:
1 x 130,763,375 = 130,763,375
and
-1 x -130,763,375 = 130,763,375
Notice both answers equal 130,763,375
With that explanation out of the way, let's continue. Next, we take the number 130,763,375 and divide it by 2:
130,763,375 ÷ 2 = 65,381,687.5
If the quotient is a whole number, then 2 and 65,381,687.5 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 | 130,763,375 | |
| -1 | -130,763,375 |
Now, we try dividing 130,763,375 by 3:
130,763,375 ÷ 3 = 43,587,791.6667
If the quotient is a whole number, then 3 and 43,587,791.6667 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 | 130,763,375 | |
| -1 | -130,763,375 |
Let's try dividing by 4:
130,763,375 ÷ 4 = 32,690,843.75
If the quotient is a whole number, then 4 and 32,690,843.75 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 | 130,763,375 | |
| -1 | 130,763,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 191 | 955 | 4,775 | 5,477 | 23,875 | 27,385 | 136,925 | 684,625 | 1,046,107 | 5,230,535 | 26,152,675 | 130,763,375 |
| -1 | -5 | -25 | -125 | -191 | -955 | -4,775 | -5,477 | -23,875 | -27,385 | -136,925 | -684,625 | -1,046,107 | -5,230,535 | -26,152,675 | -130,763,375 |
