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 580,880,345, 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 | 580,880,345 | |
| -1 | -580,880,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 580,880,345.
Example:
1 x 580,880,345 = 580,880,345
and
-1 x -580,880,345 = 580,880,345
Notice both answers equal 580,880,345
With that explanation out of the way, let's continue. Next, we take the number 580,880,345 and divide it by 2:
580,880,345 ÷ 2 = 290,440,172.5
If the quotient is a whole number, then 2 and 290,440,172.5 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 | 580,880,345 | |
| -1 | -580,880,345 |
Now, we try dividing 580,880,345 by 3:
580,880,345 ÷ 3 = 193,626,781.6667
If the quotient is a whole number, then 3 and 193,626,781.6667 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 | 580,880,345 | |
| -1 | -580,880,345 |
Let's try dividing by 4:
580,880,345 ÷ 4 = 145,220,086.25
If the quotient is a whole number, then 4 and 145,220,086.25 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 | 580,880,345 | |
| -1 | 580,880,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 103 | 365 | 515 | 7,519 | 15,451 | 37,595 | 77,255 | 1,127,923 | 1,591,453 | 5,639,615 | 7,957,265 | 116,176,069 | 580,880,345 |
| -1 | -5 | -73 | -103 | -365 | -515 | -7,519 | -15,451 | -37,595 | -77,255 | -1,127,923 | -1,591,453 | -5,639,615 | -7,957,265 | -116,176,069 | -580,880,345 |
