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 54,504,499, 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 | 54,504,499 | |
| -1 | -54,504,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,504,499.
Example:
1 x 54,504,499 = 54,504,499
and
-1 x -54,504,499 = 54,504,499
Notice both answers equal 54,504,499
With that explanation out of the way, let's continue. Next, we take the number 54,504,499 and divide it by 2:
54,504,499 ÷ 2 = 27,252,249.5
If the quotient is a whole number, then 2 and 27,252,249.5 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 | 54,504,499 | |
| -1 | -54,504,499 |
Now, we try dividing 54,504,499 by 3:
54,504,499 ÷ 3 = 18,168,166.3333
If the quotient is a whole number, then 3 and 18,168,166.3333 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 | 54,504,499 | |
| -1 | -54,504,499 |
Let's try dividing by 4:
54,504,499 ÷ 4 = 13,626,124.75
If the quotient is a whole number, then 4 and 13,626,124.75 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 | 54,504,499 | |
| -1 | 54,504,499 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 71 | 119 | 497 | 1,207 | 6,451 | 8,449 | 45,157 | 109,667 | 458,021 | 767,669 | 3,206,147 | 7,786,357 | 54,504,499 |
| -1 | -7 | -17 | -71 | -119 | -497 | -1,207 | -6,451 | -8,449 | -45,157 | -109,667 | -458,021 | -767,669 | -3,206,147 | -7,786,357 | -54,504,499 |
