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 576,776,665, 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 | 576,776,665 | |
| -1 | -576,776,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 576,776,665.
Example:
1 x 576,776,665 = 576,776,665
and
-1 x -576,776,665 = 576,776,665
Notice both answers equal 576,776,665
With that explanation out of the way, let's continue. Next, we take the number 576,776,665 and divide it by 2:
576,776,665 ÷ 2 = 288,388,332.5
If the quotient is a whole number, then 2 and 288,388,332.5 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 | 576,776,665 | |
| -1 | -576,776,665 |
Now, we try dividing 576,776,665 by 3:
576,776,665 ÷ 3 = 192,258,888.3333
If the quotient is a whole number, then 3 and 192,258,888.3333 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 | 576,776,665 | |
| -1 | -576,776,665 |
Let's try dividing by 4:
576,776,665 ÷ 4 = 144,194,166.25
If the quotient is a whole number, then 4 and 144,194,166.25 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 | 576,776,665 | |
| -1 | 576,776,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 251 | 355 | 1,255 | 6,473 | 17,821 | 32,365 | 89,105 | 459,583 | 1,624,723 | 2,297,915 | 8,123,615 | 115,355,333 | 576,776,665 |
| -1 | -5 | -71 | -251 | -355 | -1,255 | -6,473 | -17,821 | -32,365 | -89,105 | -459,583 | -1,624,723 | -2,297,915 | -8,123,615 | -115,355,333 | -576,776,665 |
