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 508,865, 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 | 508,865 | |
| -1 | -508,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 508,865.
Example:
1 x 508,865 = 508,865
and
-1 x -508,865 = 508,865
Notice both answers equal 508,865
With that explanation out of the way, let's continue. Next, we take the number 508,865 and divide it by 2:
508,865 ÷ 2 = 254,432.5
If the quotient is a whole number, then 2 and 254,432.5 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 | 508,865 | |
| -1 | -508,865 |
Now, we try dividing 508,865 by 3:
508,865 ÷ 3 = 169,621.6667
If the quotient is a whole number, then 3 and 169,621.6667 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 | 508,865 | |
| -1 | -508,865 |
Let's try dividing by 4:
508,865 ÷ 4 = 127,216.25
If the quotient is a whole number, then 4 and 127,216.25 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 | 508,865 | |
| -1 | 508,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 67 | 155 | 217 | 245 | 335 | 469 | 1,085 | 1,519 | 2,077 | 2,345 | 3,283 | 7,595 | 10,385 | 14,539 | 16,415 | 72,695 | 101,773 | 508,865 |
| -1 | -5 | -7 | -31 | -35 | -49 | -67 | -155 | -217 | -245 | -335 | -469 | -1,085 | -1,519 | -2,077 | -2,345 | -3,283 | -7,595 | -10,385 | -14,539 | -16,415 | -72,695 | -101,773 | -508,865 |
