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 130,563,265, 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 | 130,563,265 | |
| -1 | -130,563,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,563,265.
Example:
1 x 130,563,265 = 130,563,265
and
-1 x -130,563,265 = 130,563,265
Notice both answers equal 130,563,265
With that explanation out of the way, let's continue. Next, we take the number 130,563,265 and divide it by 2:
130,563,265 ÷ 2 = 65,281,632.5
If the quotient is a whole number, then 2 and 65,281,632.5 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 | 130,563,265 | |
| -1 | -130,563,265 |
Now, we try dividing 130,563,265 by 3:
130,563,265 ÷ 3 = 43,521,088.3333
If the quotient is a whole number, then 3 and 43,521,088.3333 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 | 130,563,265 | |
| -1 | -130,563,265 |
Let's try dividing by 4:
130,563,265 ÷ 4 = 32,640,816.25
If the quotient is a whole number, then 4 and 32,640,816.25 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 | 130,563,265 | |
| -1 | 130,563,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 86,753 | 433,765 | 607,271 | 3,036,355 | 3,730,379 | 18,651,895 | 26,112,653 | 130,563,265 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -86,753 | -433,765 | -607,271 | -3,036,355 | -3,730,379 | -18,651,895 | -26,112,653 | -130,563,265 |
