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 15,342,005, 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 | 15,342,005 | |
| -1 | -15,342,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,342,005.
Example:
1 x 15,342,005 = 15,342,005
and
-1 x -15,342,005 = 15,342,005
Notice both answers equal 15,342,005
With that explanation out of the way, let's continue. Next, we take the number 15,342,005 and divide it by 2:
15,342,005 ÷ 2 = 7,671,002.5
If the quotient is a whole number, then 2 and 7,671,002.5 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 | 15,342,005 | |
| -1 | -15,342,005 |
Now, we try dividing 15,342,005 by 3:
15,342,005 ÷ 3 = 5,114,001.6667
If the quotient is a whole number, then 3 and 5,114,001.6667 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 | 15,342,005 | |
| -1 | -15,342,005 |
Let's try dividing by 4:
15,342,005 ÷ 4 = 3,835,501.25
If the quotient is a whole number, then 4 and 3,835,501.25 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 | 15,342,005 | |
| -1 | 15,342,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 97 | 485 | 679 | 3,395 | 4,519 | 22,595 | 31,633 | 158,165 | 438,343 | 2,191,715 | 3,068,401 | 15,342,005 |
| -1 | -5 | -7 | -35 | -97 | -485 | -679 | -3,395 | -4,519 | -22,595 | -31,633 | -158,165 | -438,343 | -2,191,715 | -3,068,401 | -15,342,005 |
