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 55,811,345, 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 | 55,811,345 | |
| -1 | -55,811,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,811,345.
Example:
1 x 55,811,345 = 55,811,345
and
-1 x -55,811,345 = 55,811,345
Notice both answers equal 55,811,345
With that explanation out of the way, let's continue. Next, we take the number 55,811,345 and divide it by 2:
55,811,345 ÷ 2 = 27,905,672.5
If the quotient is a whole number, then 2 and 27,905,672.5 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 | 55,811,345 | |
| -1 | -55,811,345 |
Now, we try dividing 55,811,345 by 3:
55,811,345 ÷ 3 = 18,603,781.6667
If the quotient is a whole number, then 3 and 18,603,781.6667 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 | 55,811,345 | |
| -1 | -55,811,345 |
Let's try dividing by 4:
55,811,345 ÷ 4 = 13,952,836.25
If the quotient is a whole number, then 4 and 13,952,836.25 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 | 55,811,345 | |
| -1 | 55,811,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 277 | 295 | 683 | 1,385 | 3,415 | 16,343 | 40,297 | 81,715 | 189,191 | 201,485 | 945,955 | 11,162,269 | 55,811,345 |
| -1 | -5 | -59 | -277 | -295 | -683 | -1,385 | -3,415 | -16,343 | -40,297 | -81,715 | -189,191 | -201,485 | -945,955 | -11,162,269 | -55,811,345 |
