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 797,525, 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 | 797,525 | |
| -1 | -797,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 797,525.
Example:
1 x 797,525 = 797,525
and
-1 x -797,525 = 797,525
Notice both answers equal 797,525
With that explanation out of the way, let's continue. Next, we take the number 797,525 and divide it by 2:
797,525 ÷ 2 = 398,762.5
If the quotient is a whole number, then 2 and 398,762.5 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 | 797,525 | |
| -1 | -797,525 |
Now, we try dividing 797,525 by 3:
797,525 ÷ 3 = 265,841.6667
If the quotient is a whole number, then 3 and 265,841.6667 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 | 797,525 | |
| -1 | -797,525 |
Let's try dividing by 4:
797,525 ÷ 4 = 199,381.25
If the quotient is a whole number, then 4 and 199,381.25 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 | 797,525 | |
| -1 | 797,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 25 | 73 | 95 | 115 | 365 | 437 | 475 | 575 | 1,387 | 1,679 | 1,825 | 2,185 | 6,935 | 8,395 | 10,925 | 31,901 | 34,675 | 41,975 | 159,505 | 797,525 |
| -1 | -5 | -19 | -23 | -25 | -73 | -95 | -115 | -365 | -437 | -475 | -575 | -1,387 | -1,679 | -1,825 | -2,185 | -6,935 | -8,395 | -10,925 | -31,901 | -34,675 | -41,975 | -159,505 | -797,525 |
