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 253,825, 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 | 253,825 | |
| -1 | -253,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,825.
Example:
1 x 253,825 = 253,825
and
-1 x -253,825 = 253,825
Notice both answers equal 253,825
With that explanation out of the way, let's continue. Next, we take the number 253,825 and divide it by 2:
253,825 ÷ 2 = 126,912.5
If the quotient is a whole number, then 2 and 126,912.5 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 | 253,825 | |
| -1 | -253,825 |
Now, we try dividing 253,825 by 3:
253,825 ÷ 3 = 84,608.3333
If the quotient is a whole number, then 3 and 84,608.3333 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 | 253,825 | |
| -1 | -253,825 |
Let's try dividing by 4:
253,825 ÷ 4 = 63,456.25
If the quotient is a whole number, then 4 and 63,456.25 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 | 253,825 | |
| -1 | 253,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 71 | 143 | 275 | 325 | 355 | 715 | 781 | 923 | 1,775 | 3,575 | 3,905 | 4,615 | 10,153 | 19,525 | 23,075 | 50,765 | 253,825 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -71 | -143 | -275 | -325 | -355 | -715 | -781 | -923 | -1,775 | -3,575 | -3,905 | -4,615 | -10,153 | -19,525 | -23,075 | -50,765 | -253,825 |
