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 65,775,055, 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 | 65,775,055 | |
| -1 | -65,775,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,775,055.
Example:
1 x 65,775,055 = 65,775,055
and
-1 x -65,775,055 = 65,775,055
Notice both answers equal 65,775,055
With that explanation out of the way, let's continue. Next, we take the number 65,775,055 and divide it by 2:
65,775,055 ÷ 2 = 32,887,527.5
If the quotient is a whole number, then 2 and 32,887,527.5 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 | 65,775,055 | |
| -1 | -65,775,055 |
Now, we try dividing 65,775,055 by 3:
65,775,055 ÷ 3 = 21,925,018.3333
If the quotient is a whole number, then 3 and 21,925,018.3333 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 | 65,775,055 | |
| -1 | -65,775,055 |
Let's try dividing by 4:
65,775,055 ÷ 4 = 16,443,763.75
If the quotient is a whole number, then 4 and 16,443,763.75 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 | 65,775,055 | |
| -1 | 65,775,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 30,103 | 150,515 | 571,957 | 692,369 | 2,859,785 | 3,461,845 | 13,155,011 | 65,775,055 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -30,103 | -150,515 | -571,957 | -692,369 | -2,859,785 | -3,461,845 | -13,155,011 | -65,775,055 |
