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 888,486,005, 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 | 888,486,005 | |
| -1 | -888,486,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 888,486,005.
Example:
1 x 888,486,005 = 888,486,005
and
-1 x -888,486,005 = 888,486,005
Notice both answers equal 888,486,005
With that explanation out of the way, let's continue. Next, we take the number 888,486,005 and divide it by 2:
888,486,005 ÷ 2 = 444,243,002.5
If the quotient is a whole number, then 2 and 444,243,002.5 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 | 888,486,005 | |
| -1 | -888,486,005 |
Now, we try dividing 888,486,005 by 3:
888,486,005 ÷ 3 = 296,162,001.6667
If the quotient is a whole number, then 3 and 296,162,001.6667 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 | 888,486,005 | |
| -1 | -888,486,005 |
Let's try dividing by 4:
888,486,005 ÷ 4 = 222,121,501.25
If the quotient is a whole number, then 4 and 222,121,501.25 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 | 888,486,005 | |
| -1 | 888,486,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 991 | 4,955 | 10,901 | 16,301 | 54,505 | 81,505 | 179,311 | 896,555 | 16,154,291 | 80,771,455 | 177,697,201 | 888,486,005 |
| -1 | -5 | -11 | -55 | -991 | -4,955 | -10,901 | -16,301 | -54,505 | -81,505 | -179,311 | -896,555 | -16,154,291 | -80,771,455 | -177,697,201 | -888,486,005 |
