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 301,442,005, 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 | 301,442,005 | |
| -1 | -301,442,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 301,442,005.
Example:
1 x 301,442,005 = 301,442,005
and
-1 x -301,442,005 = 301,442,005
Notice both answers equal 301,442,005
With that explanation out of the way, let's continue. Next, we take the number 301,442,005 and divide it by 2:
301,442,005 ÷ 2 = 150,721,002.5
If the quotient is a whole number, then 2 and 150,721,002.5 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 | 301,442,005 | |
| -1 | -301,442,005 |
Now, we try dividing 301,442,005 by 3:
301,442,005 ÷ 3 = 100,480,668.3333
If the quotient is a whole number, then 3 and 100,480,668.3333 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 | 301,442,005 | |
| -1 | -301,442,005 |
Let's try dividing by 4:
301,442,005 ÷ 4 = 75,360,501.25
If the quotient is a whole number, then 4 and 75,360,501.25 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 | 301,442,005 | |
| -1 | 301,442,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 107 | 265 | 535 | 5,671 | 10,631 | 28,355 | 53,155 | 563,443 | 1,137,517 | 2,817,215 | 5,687,585 | 60,288,401 | 301,442,005 |
| -1 | -5 | -53 | -107 | -265 | -535 | -5,671 | -10,631 | -28,355 | -53,155 | -563,443 | -1,137,517 | -2,817,215 | -5,687,585 | -60,288,401 | -301,442,005 |
