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 55,523,017, 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 | 55,523,017 | |
| -1 | -55,523,017 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,523,017.
Example:
1 x 55,523,017 = 55,523,017
and
-1 x -55,523,017 = 55,523,017
Notice both answers equal 55,523,017
With that explanation out of the way, let's continue. Next, we take the number 55,523,017 and divide it by 2:
55,523,017 ÷ 2 = 27,761,508.5
If the quotient is a whole number, then 2 and 27,761,508.5 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 | 55,523,017 | |
| -1 | -55,523,017 |
Now, we try dividing 55,523,017 by 3:
55,523,017 ÷ 3 = 18,507,672.3333
If the quotient is a whole number, then 3 and 18,507,672.3333 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 | 55,523,017 | |
| -1 | -55,523,017 |
Let's try dividing by 4:
55,523,017 ÷ 4 = 13,880,754.25
If the quotient is a whole number, then 4 and 13,880,754.25 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 | 55,523,017 | |
| -1 | 55,523,017 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 181 | 353 | 869 | 1,991 | 3,883 | 14,299 | 27,887 | 63,893 | 157,289 | 306,757 | 702,823 | 5,047,547 | 55,523,017 |
| -1 | -11 | -79 | -181 | -353 | -869 | -1,991 | -3,883 | -14,299 | -27,887 | -63,893 | -157,289 | -306,757 | -702,823 | -5,047,547 | -55,523,017 |
