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 55,716,055, 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 | 55,716,055 | |
| -1 | -55,716,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,716,055.
Example:
1 x 55,716,055 = 55,716,055
and
-1 x -55,716,055 = 55,716,055
Notice both answers equal 55,716,055
With that explanation out of the way, let's continue. Next, we take the number 55,716,055 and divide it by 2:
55,716,055 ÷ 2 = 27,858,027.5
If the quotient is a whole number, then 2 and 27,858,027.5 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 | 55,716,055 | |
| -1 | -55,716,055 |
Now, we try dividing 55,716,055 by 3:
55,716,055 ÷ 3 = 18,572,018.3333
If the quotient is a whole number, then 3 and 18,572,018.3333 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 | 55,716,055 | |
| -1 | -55,716,055 |
Let's try dividing by 4:
55,716,055 ÷ 4 = 13,929,013.75
If the quotient is a whole number, then 4 and 13,929,013.75 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 | 55,716,055 | |
| -1 | 55,716,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 347 | 1,735 | 1,889 | 5,899 | 9,445 | 29,495 | 32,113 | 160,565 | 655,483 | 3,277,415 | 11,143,211 | 55,716,055 |
| -1 | -5 | -17 | -85 | -347 | -1,735 | -1,889 | -5,899 | -9,445 | -29,495 | -32,113 | -160,565 | -655,483 | -3,277,415 | -11,143,211 | -55,716,055 |
