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 55,260,115, 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 | 55,260,115 | |
| -1 | -55,260,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,260,115.
Example:
1 x 55,260,115 = 55,260,115
and
-1 x -55,260,115 = 55,260,115
Notice both answers equal 55,260,115
With that explanation out of the way, let's continue. Next, we take the number 55,260,115 and divide it by 2:
55,260,115 ÷ 2 = 27,630,057.5
If the quotient is a whole number, then 2 and 27,630,057.5 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 | 55,260,115 | |
| -1 | -55,260,115 |
Now, we try dividing 55,260,115 by 3:
55,260,115 ÷ 3 = 18,420,038.3333
If the quotient is a whole number, then 3 and 18,420,038.3333 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 | 55,260,115 | |
| -1 | -55,260,115 |
Let's try dividing by 4:
55,260,115 ÷ 4 = 13,815,028.75
If the quotient is a whole number, then 4 and 13,815,028.75 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 | 55,260,115 | |
| -1 | 55,260,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 277 | 1,385 | 2,347 | 4,709 | 11,735 | 23,545 | 39,899 | 199,495 | 650,119 | 3,250,595 | 11,052,023 | 55,260,115 |
| -1 | -5 | -17 | -85 | -277 | -1,385 | -2,347 | -4,709 | -11,735 | -23,545 | -39,899 | -199,495 | -650,119 | -3,250,595 | -11,052,023 | -55,260,115 |
