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 55,078,249, 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 | 55,078,249 | |
| -1 | -55,078,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,078,249.
Example:
1 x 55,078,249 = 55,078,249
and
-1 x -55,078,249 = 55,078,249
Notice both answers equal 55,078,249
With that explanation out of the way, let's continue. Next, we take the number 55,078,249 and divide it by 2:
55,078,249 ÷ 2 = 27,539,124.5
If the quotient is a whole number, then 2 and 27,539,124.5 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 | 55,078,249 | |
| -1 | -55,078,249 |
Now, we try dividing 55,078,249 by 3:
55,078,249 ÷ 3 = 18,359,416.3333
If the quotient is a whole number, then 3 and 18,359,416.3333 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 | 55,078,249 | |
| -1 | -55,078,249 |
Let's try dividing by 4:
55,078,249 ÷ 4 = 13,769,562.25
If the quotient is a whole number, then 4 and 13,769,562.25 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 | 55,078,249 | |
| -1 | 55,078,249 |
If you did it right, you will end up with this table:
| 1 | 17 | 97 | 127 | 263 | 1,649 | 2,159 | 4,471 | 12,319 | 25,511 | 33,401 | 209,423 | 433,687 | 567,817 | 3,239,897 | 55,078,249 |
| -1 | -17 | -97 | -127 | -263 | -1,649 | -2,159 | -4,471 | -12,319 | -25,511 | -33,401 | -209,423 | -433,687 | -567,817 | -3,239,897 | -55,078,249 |
