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 15,234,115, 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 | 15,234,115 | |
| -1 | -15,234,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,234,115.
Example:
1 x 15,234,115 = 15,234,115
and
-1 x -15,234,115 = 15,234,115
Notice both answers equal 15,234,115
With that explanation out of the way, let's continue. Next, we take the number 15,234,115 and divide it by 2:
15,234,115 ÷ 2 = 7,617,057.5
If the quotient is a whole number, then 2 and 7,617,057.5 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 | 15,234,115 | |
| -1 | -15,234,115 |
Now, we try dividing 15,234,115 by 3:
15,234,115 ÷ 3 = 5,078,038.3333
If the quotient is a whole number, then 3 and 5,078,038.3333 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 | 15,234,115 | |
| -1 | -15,234,115 |
Let's try dividing by 4:
15,234,115 ÷ 4 = 3,808,528.75
If the quotient is a whole number, then 4 and 3,808,528.75 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 | 15,234,115 | |
| -1 | 15,234,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 71 | 355 | 923 | 3,301 | 4,615 | 16,505 | 42,913 | 214,565 | 234,371 | 1,171,855 | 3,046,823 | 15,234,115 |
| -1 | -5 | -13 | -65 | -71 | -355 | -923 | -3,301 | -4,615 | -16,505 | -42,913 | -214,565 | -234,371 | -1,171,855 | -3,046,823 | -15,234,115 |
