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 365,005,055, 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 | 365,005,055 | |
| -1 | -365,005,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 365,005,055.
Example:
1 x 365,005,055 = 365,005,055
and
-1 x -365,005,055 = 365,005,055
Notice both answers equal 365,005,055
With that explanation out of the way, let's continue. Next, we take the number 365,005,055 and divide it by 2:
365,005,055 ÷ 2 = 182,502,527.5
If the quotient is a whole number, then 2 and 182,502,527.5 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 | 365,005,055 | |
| -1 | -365,005,055 |
Now, we try dividing 365,005,055 by 3:
365,005,055 ÷ 3 = 121,668,351.6667
If the quotient is a whole number, then 3 and 121,668,351.6667 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 | 365,005,055 | |
| -1 | -365,005,055 |
Let's try dividing by 4:
365,005,055 ÷ 4 = 91,251,263.75
If the quotient is a whole number, then 4 and 91,251,263.75 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 | 365,005,055 | |
| -1 | 365,005,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 47 | 115 | 235 | 1,081 | 5,405 | 67,531 | 337,655 | 1,553,213 | 3,173,957 | 7,766,065 | 15,869,785 | 73,001,011 | 365,005,055 |
| -1 | -5 | -23 | -47 | -115 | -235 | -1,081 | -5,405 | -67,531 | -337,655 | -1,553,213 | -3,173,957 | -7,766,065 | -15,869,785 | -73,001,011 | -365,005,055 |
