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 55,205,545, 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 | 55,205,545 | |
| -1 | -55,205,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,205,545.
Example:
1 x 55,205,545 = 55,205,545
and
-1 x -55,205,545 = 55,205,545
Notice both answers equal 55,205,545
With that explanation out of the way, let's continue. Next, we take the number 55,205,545 and divide it by 2:
55,205,545 ÷ 2 = 27,602,772.5
If the quotient is a whole number, then 2 and 27,602,772.5 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 | 55,205,545 | |
| -1 | -55,205,545 |
Now, we try dividing 55,205,545 by 3:
55,205,545 ÷ 3 = 18,401,848.3333
If the quotient is a whole number, then 3 and 18,401,848.3333 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 | 55,205,545 | |
| -1 | -55,205,545 |
Let's try dividing by 4:
55,205,545 ÷ 4 = 13,801,386.25
If the quotient is a whole number, then 4 and 13,801,386.25 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 | 55,205,545 | |
| -1 | 55,205,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 34,183 | 170,915 | 581,111 | 649,477 | 2,905,555 | 3,247,385 | 11,041,109 | 55,205,545 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -34,183 | -170,915 | -581,111 | -649,477 | -2,905,555 | -3,247,385 | -11,041,109 | -55,205,545 |
