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 613,025, 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 | 613,025 | |
| -1 | -613,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 613,025.
Example:
1 x 613,025 = 613,025
and
-1 x -613,025 = 613,025
Notice both answers equal 613,025
With that explanation out of the way, let's continue. Next, we take the number 613,025 and divide it by 2:
613,025 ÷ 2 = 306,512.5
If the quotient is a whole number, then 2 and 306,512.5 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 | 613,025 | |
| -1 | -613,025 |
Now, we try dividing 613,025 by 3:
613,025 ÷ 3 = 204,341.6667
If the quotient is a whole number, then 3 and 204,341.6667 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 | 613,025 | |
| -1 | -613,025 |
Let's try dividing by 4:
613,025 ÷ 4 = 153,256.25
If the quotient is a whole number, then 4 and 153,256.25 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 | 613,025 | |
| -1 | 613,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 113 | 155 | 175 | 217 | 565 | 775 | 791 | 1,085 | 2,825 | 3,503 | 3,955 | 5,425 | 17,515 | 19,775 | 24,521 | 87,575 | 122,605 | 613,025 |
| -1 | -5 | -7 | -25 | -31 | -35 | -113 | -155 | -175 | -217 | -565 | -775 | -791 | -1,085 | -2,825 | -3,503 | -3,955 | -5,425 | -17,515 | -19,775 | -24,521 | -87,575 | -122,605 | -613,025 |
