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 54,545,239, 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 | 54,545,239 | |
| -1 | -54,545,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,545,239.
Example:
1 x 54,545,239 = 54,545,239
and
-1 x -54,545,239 = 54,545,239
Notice both answers equal 54,545,239
With that explanation out of the way, let's continue. Next, we take the number 54,545,239 and divide it by 2:
54,545,239 ÷ 2 = 27,272,619.5
If the quotient is a whole number, then 2 and 27,272,619.5 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 | 54,545,239 | |
| -1 | -54,545,239 |
Now, we try dividing 54,545,239 by 3:
54,545,239 ÷ 3 = 18,181,746.3333
If the quotient is a whole number, then 3 and 18,181,746.3333 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 | 54,545,239 | |
| -1 | -54,545,239 |
Let's try dividing by 4:
54,545,239 ÷ 4 = 13,636,309.75
If the quotient is a whole number, then 4 and 13,636,309.75 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 | 54,545,239 | |
| -1 | 54,545,239 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 317 | 329 | 523 | 2,219 | 3,661 | 14,899 | 24,581 | 104,293 | 165,791 | 172,067 | 1,160,537 | 7,792,177 | 54,545,239 |
| -1 | -7 | -47 | -317 | -329 | -523 | -2,219 | -3,661 | -14,899 | -24,581 | -104,293 | -165,791 | -172,067 | -1,160,537 | -7,792,177 | -54,545,239 |
