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 360,665,455, 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 | 360,665,455 | |
| -1 | -360,665,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 360,665,455.
Example:
1 x 360,665,455 = 360,665,455
and
-1 x -360,665,455 = 360,665,455
Notice both answers equal 360,665,455
With that explanation out of the way, let's continue. Next, we take the number 360,665,455 and divide it by 2:
360,665,455 ÷ 2 = 180,332,727.5
If the quotient is a whole number, then 2 and 180,332,727.5 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 | 360,665,455 | |
| -1 | -360,665,455 |
Now, we try dividing 360,665,455 by 3:
360,665,455 ÷ 3 = 120,221,818.3333
If the quotient is a whole number, then 3 and 120,221,818.3333 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 | 360,665,455 | |
| -1 | -360,665,455 |
Let's try dividing by 4:
360,665,455 ÷ 4 = 90,166,363.75
If the quotient is a whole number, then 4 and 90,166,363.75 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 | 360,665,455 | |
| -1 | 360,665,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 3,145 | 114,679 | 573,395 | 1,949,543 | 4,243,123 | 9,747,715 | 21,215,615 | 72,133,091 | 360,665,455 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -3,145 | -114,679 | -573,395 | -1,949,543 | -4,243,123 | -9,747,715 | -21,215,615 | -72,133,091 | -360,665,455 |
