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 15,054,523, 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 | 15,054,523 | |
| -1 | -15,054,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,054,523.
Example:
1 x 15,054,523 = 15,054,523
and
-1 x -15,054,523 = 15,054,523
Notice both answers equal 15,054,523
With that explanation out of the way, let's continue. Next, we take the number 15,054,523 and divide it by 2:
15,054,523 ÷ 2 = 7,527,261.5
If the quotient is a whole number, then 2 and 7,527,261.5 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 | 15,054,523 | |
| -1 | -15,054,523 |
Now, we try dividing 15,054,523 by 3:
15,054,523 ÷ 3 = 5,018,174.3333
If the quotient is a whole number, then 3 and 5,018,174.3333 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 | 15,054,523 | |
| -1 | -15,054,523 |
Let's try dividing by 4:
15,054,523 ÷ 4 = 3,763,630.75
If the quotient is a whole number, then 4 and 3,763,630.75 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 | 15,054,523 | |
| -1 | 15,054,523 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 47 | 407 | 517 | 787 | 1,739 | 8,657 | 19,129 | 29,119 | 36,989 | 320,309 | 406,879 | 1,368,593 | 15,054,523 |
| -1 | -11 | -37 | -47 | -407 | -517 | -787 | -1,739 | -8,657 | -19,129 | -29,119 | -36,989 | -320,309 | -406,879 | -1,368,593 | -15,054,523 |
