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 55,010,155, 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 | 55,010,155 | |
| -1 | -55,010,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,010,155.
Example:
1 x 55,010,155 = 55,010,155
and
-1 x -55,010,155 = 55,010,155
Notice both answers equal 55,010,155
With that explanation out of the way, let's continue. Next, we take the number 55,010,155 and divide it by 2:
55,010,155 ÷ 2 = 27,505,077.5
If the quotient is a whole number, then 2 and 27,505,077.5 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 | 55,010,155 | |
| -1 | -55,010,155 |
Now, we try dividing 55,010,155 by 3:
55,010,155 ÷ 3 = 18,336,718.3333
If the quotient is a whole number, then 3 and 18,336,718.3333 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 | 55,010,155 | |
| -1 | -55,010,155 |
Let's try dividing by 4:
55,010,155 ÷ 4 = 13,752,538.75
If the quotient is a whole number, then 4 and 13,752,538.75 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 | 55,010,155 | |
| -1 | 55,010,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 101 | 485 | 505 | 1,123 | 5,615 | 9,797 | 48,985 | 108,931 | 113,423 | 544,655 | 567,115 | 11,002,031 | 55,010,155 |
| -1 | -5 | -97 | -101 | -485 | -505 | -1,123 | -5,615 | -9,797 | -48,985 | -108,931 | -113,423 | -544,655 | -567,115 | -11,002,031 | -55,010,155 |
