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 606,105,655, 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 | 606,105,655 | |
| -1 | -606,105,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 606,105,655.
Example:
1 x 606,105,655 = 606,105,655
and
-1 x -606,105,655 = 606,105,655
Notice both answers equal 606,105,655
With that explanation out of the way, let's continue. Next, we take the number 606,105,655 and divide it by 2:
606,105,655 ÷ 2 = 303,052,827.5
If the quotient is a whole number, then 2 and 303,052,827.5 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 | 606,105,655 | |
| -1 | -606,105,655 |
Now, we try dividing 606,105,655 by 3:
606,105,655 ÷ 3 = 202,035,218.3333
If the quotient is a whole number, then 3 and 202,035,218.3333 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 | 606,105,655 | |
| -1 | -606,105,655 |
Let's try dividing by 4:
606,105,655 ÷ 4 = 151,526,413.75
If the quotient is a whole number, then 4 and 151,526,413.75 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 | 606,105,655 | |
| -1 | 606,105,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 47 | 145 | 235 | 1,363 | 6,815 | 88,937 | 444,685 | 2,579,173 | 4,180,039 | 12,895,865 | 20,900,195 | 121,221,131 | 606,105,655 |
| -1 | -5 | -29 | -47 | -145 | -235 | -1,363 | -6,815 | -88,937 | -444,685 | -2,579,173 | -4,180,039 | -12,895,865 | -20,900,195 | -121,221,131 | -606,105,655 |
