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 360,435,005, 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 | 360,435,005 | |
| -1 | -360,435,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 360,435,005.
Example:
1 x 360,435,005 = 360,435,005
and
-1 x -360,435,005 = 360,435,005
Notice both answers equal 360,435,005
With that explanation out of the way, let's continue. Next, we take the number 360,435,005 and divide it by 2:
360,435,005 ÷ 2 = 180,217,502.5
If the quotient is a whole number, then 2 and 180,217,502.5 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 | 360,435,005 | |
| -1 | -360,435,005 |
Now, we try dividing 360,435,005 by 3:
360,435,005 ÷ 3 = 120,145,001.6667
If the quotient is a whole number, then 3 and 120,145,001.6667 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 | 360,435,005 | |
| -1 | -360,435,005 |
Let's try dividing by 4:
360,435,005 ÷ 4 = 90,108,751.25
If the quotient is a whole number, then 4 and 90,108,751.25 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 | 360,435,005 | |
| -1 | 360,435,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 311 | 1,555 | 2,177 | 10,885 | 33,113 | 165,565 | 231,791 | 1,158,955 | 10,298,143 | 51,490,715 | 72,087,001 | 360,435,005 |
| -1 | -5 | -7 | -35 | -311 | -1,555 | -2,177 | -10,885 | -33,113 | -165,565 | -231,791 | -1,158,955 | -10,298,143 | -51,490,715 | -72,087,001 | -360,435,005 |
