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 805,880,365, 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 | 805,880,365 | |
| -1 | -805,880,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 805,880,365.
Example:
1 x 805,880,365 = 805,880,365
and
-1 x -805,880,365 = 805,880,365
Notice both answers equal 805,880,365
With that explanation out of the way, let's continue. Next, we take the number 805,880,365 and divide it by 2:
805,880,365 ÷ 2 = 402,940,182.5
If the quotient is a whole number, then 2 and 402,940,182.5 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 | 805,880,365 | |
| -1 | -805,880,365 |
Now, we try dividing 805,880,365 by 3:
805,880,365 ÷ 3 = 268,626,788.3333
If the quotient is a whole number, then 3 and 268,626,788.3333 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 | 805,880,365 | |
| -1 | -805,880,365 |
Let's try dividing by 4:
805,880,365 ÷ 4 = 201,470,091.25
If the quotient is a whole number, then 4 and 201,470,091.25 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 | 805,880,365 | |
| -1 | 805,880,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 485 | 719 | 2,311 | 3,595 | 11,555 | 69,743 | 224,167 | 348,715 | 1,120,835 | 1,661,609 | 8,308,045 | 161,176,073 | 805,880,365 |
| -1 | -5 | -97 | -485 | -719 | -2,311 | -3,595 | -11,555 | -69,743 | -224,167 | -348,715 | -1,120,835 | -1,661,609 | -8,308,045 | -161,176,073 | -805,880,365 |
