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 130,424,441, 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 | 130,424,441 | |
| -1 | -130,424,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,424,441.
Example:
1 x 130,424,441 = 130,424,441
and
-1 x -130,424,441 = 130,424,441
Notice both answers equal 130,424,441
With that explanation out of the way, let's continue. Next, we take the number 130,424,441 and divide it by 2:
130,424,441 ÷ 2 = 65,212,220.5
If the quotient is a whole number, then 2 and 65,212,220.5 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 | 130,424,441 | |
| -1 | -130,424,441 |
Now, we try dividing 130,424,441 by 3:
130,424,441 ÷ 3 = 43,474,813.6667
If the quotient is a whole number, then 3 and 43,474,813.6667 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 | 130,424,441 | |
| -1 | -130,424,441 |
Let's try dividing by 4:
130,424,441 ÷ 4 = 32,606,110.25
If the quotient is a whole number, then 4 and 32,606,110.25 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 | 130,424,441 | |
| -1 | 130,424,441 |
If you did it right, you will end up with this table:
| 1 | 7 | 197 | 271 | 349 | 1,379 | 1,897 | 2,443 | 53,387 | 68,753 | 94,579 | 373,709 | 481,271 | 662,053 | 18,632,063 | 130,424,441 |
| -1 | -7 | -197 | -271 | -349 | -1,379 | -1,897 | -2,443 | -53,387 | -68,753 | -94,579 | -373,709 | -481,271 | -662,053 | -18,632,063 | -130,424,441 |
