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 600,005, 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 | 600,005 | |
| -1 | -600,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 600,005.
Example:
1 x 600,005 = 600,005
and
-1 x -600,005 = 600,005
Notice both answers equal 600,005
With that explanation out of the way, let's continue. Next, we take the number 600,005 and divide it by 2:
600,005 ÷ 2 = 300,002.5
If the quotient is a whole number, then 2 and 300,002.5 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 | 600,005 | |
| -1 | -600,005 |
Now, we try dividing 600,005 by 3:
600,005 ÷ 3 = 200,001.6667
If the quotient is a whole number, then 3 and 200,001.6667 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 | 600,005 | |
| -1 | -600,005 |
Let's try dividing by 4:
600,005 ÷ 4 = 150,001.25
If the quotient is a whole number, then 4 and 150,001.25 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 | 600,005 | |
| -1 | 600,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 79 | 155 | 217 | 245 | 395 | 553 | 1,085 | 1,519 | 2,449 | 2,765 | 3,871 | 7,595 | 12,245 | 17,143 | 19,355 | 85,715 | 120,001 | 600,005 |
| -1 | -5 | -7 | -31 | -35 | -49 | -79 | -155 | -217 | -245 | -395 | -553 | -1,085 | -1,519 | -2,449 | -2,765 | -3,871 | -7,595 | -12,245 | -17,143 | -19,355 | -85,715 | -120,001 | -600,005 |
