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 65,083,055, 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 | 65,083,055 | |
| -1 | -65,083,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,083,055.
Example:
1 x 65,083,055 = 65,083,055
and
-1 x -65,083,055 = 65,083,055
Notice both answers equal 65,083,055
With that explanation out of the way, let's continue. Next, we take the number 65,083,055 and divide it by 2:
65,083,055 ÷ 2 = 32,541,527.5
If the quotient is a whole number, then 2 and 32,541,527.5 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 | 65,083,055 | |
| -1 | -65,083,055 |
Now, we try dividing 65,083,055 by 3:
65,083,055 ÷ 3 = 21,694,351.6667
If the quotient is a whole number, then 3 and 21,694,351.6667 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 | 65,083,055 | |
| -1 | -65,083,055 |
Let's try dividing by 4:
65,083,055 ÷ 4 = 16,270,763.75
If the quotient is a whole number, then 4 and 16,270,763.75 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 | 65,083,055 | |
| -1 | 65,083,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 127 | 635 | 2,159 | 6,029 | 10,795 | 30,145 | 102,493 | 512,465 | 765,683 | 3,828,415 | 13,016,611 | 65,083,055 |
| -1 | -5 | -17 | -85 | -127 | -635 | -2,159 | -6,029 | -10,795 | -30,145 | -102,493 | -512,465 | -765,683 | -3,828,415 | -13,016,611 | -65,083,055 |
