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 55,534,415, 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 | 55,534,415 | |
| -1 | -55,534,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,534,415.
Example:
1 x 55,534,415 = 55,534,415
and
-1 x -55,534,415 = 55,534,415
Notice both answers equal 55,534,415
With that explanation out of the way, let's continue. Next, we take the number 55,534,415 and divide it by 2:
55,534,415 ÷ 2 = 27,767,207.5
If the quotient is a whole number, then 2 and 27,767,207.5 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 | 55,534,415 | |
| -1 | -55,534,415 |
Now, we try dividing 55,534,415 by 3:
55,534,415 ÷ 3 = 18,511,471.6667
If the quotient is a whole number, then 3 and 18,511,471.6667 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 | 55,534,415 | |
| -1 | -55,534,415 |
Let's try dividing by 4:
55,534,415 ÷ 4 = 13,883,603.75
If the quotient is a whole number, then 4 and 13,883,603.75 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 | 55,534,415 | |
| -1 | 55,534,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 113 | 227 | 433 | 565 | 1,135 | 2,165 | 25,651 | 48,929 | 98,291 | 128,255 | 244,645 | 491,455 | 11,106,883 | 55,534,415 |
| -1 | -5 | -113 | -227 | -433 | -565 | -1,135 | -2,165 | -25,651 | -48,929 | -98,291 | -128,255 | -244,645 | -491,455 | -11,106,883 | -55,534,415 |
