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 360,311,605, 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 | 360,311,605 | |
| -1 | -360,311,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 360,311,605.
Example:
1 x 360,311,605 = 360,311,605
and
-1 x -360,311,605 = 360,311,605
Notice both answers equal 360,311,605
With that explanation out of the way, let's continue. Next, we take the number 360,311,605 and divide it by 2:
360,311,605 ÷ 2 = 180,155,802.5
If the quotient is a whole number, then 2 and 180,155,802.5 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 | 360,311,605 | |
| -1 | -360,311,605 |
Now, we try dividing 360,311,605 by 3:
360,311,605 ÷ 3 = 120,103,868.3333
If the quotient is a whole number, then 3 and 120,103,868.3333 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 | 360,311,605 | |
| -1 | -360,311,605 |
Let's try dividing by 4:
360,311,605 ÷ 4 = 90,077,901.25
If the quotient is a whole number, then 4 and 90,077,901.25 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 | 360,311,605 | |
| -1 | 360,311,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 89 | 155 | 445 | 2,759 | 13,795 | 26,119 | 130,595 | 809,689 | 2,324,591 | 4,048,445 | 11,622,955 | 72,062,321 | 360,311,605 |
| -1 | -5 | -31 | -89 | -155 | -445 | -2,759 | -13,795 | -26,119 | -130,595 | -809,689 | -2,324,591 | -4,048,445 | -11,622,955 | -72,062,321 | -360,311,605 |
