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 617,015, 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 | 617,015 | |
| -1 | -617,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 617,015.
Example:
1 x 617,015 = 617,015
and
-1 x -617,015 = 617,015
Notice both answers equal 617,015
With that explanation out of the way, let's continue. Next, we take the number 617,015 and divide it by 2:
617,015 ÷ 2 = 308,507.5
If the quotient is a whole number, then 2 and 308,507.5 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 | 617,015 | |
| -1 | -617,015 |
Now, we try dividing 617,015 by 3:
617,015 ÷ 3 = 205,671.6667
If the quotient is a whole number, then 3 and 205,671.6667 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 | 617,015 | |
| -1 | -617,015 |
Let's try dividing by 4:
617,015 ÷ 4 = 154,253.75
If the quotient is a whole number, then 4 and 154,253.75 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 | 617,015 | |
| -1 | 617,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 61 | 85 | 119 | 289 | 305 | 427 | 595 | 1,037 | 1,445 | 2,023 | 2,135 | 5,185 | 7,259 | 10,115 | 17,629 | 36,295 | 88,145 | 123,403 | 617,015 |
| -1 | -5 | -7 | -17 | -35 | -61 | -85 | -119 | -289 | -305 | -427 | -595 | -1,037 | -1,445 | -2,023 | -2,135 | -5,185 | -7,259 | -10,115 | -17,629 | -36,295 | -88,145 | -123,403 | -617,015 |
