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 248,675, 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 | 248,675 | |
| -1 | -248,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 248,675.
Example:
1 x 248,675 = 248,675
and
-1 x -248,675 = 248,675
Notice both answers equal 248,675
With that explanation out of the way, let's continue. Next, we take the number 248,675 and divide it by 2:
248,675 ÷ 2 = 124,337.5
If the quotient is a whole number, then 2 and 124,337.5 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 | 248,675 | |
| -1 | -248,675 |
Now, we try dividing 248,675 by 3:
248,675 ÷ 3 = 82,891.6667
If the quotient is a whole number, then 3 and 82,891.6667 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 | 248,675 | |
| -1 | -248,675 |
Let's try dividing by 4:
248,675 ÷ 4 = 62,168.75
If the quotient is a whole number, then 4 and 62,168.75 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 | 248,675 | |
| -1 | 248,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 49 | 145 | 175 | 203 | 245 | 343 | 725 | 1,015 | 1,225 | 1,421 | 1,715 | 5,075 | 7,105 | 8,575 | 9,947 | 35,525 | 49,735 | 248,675 |
| -1 | -5 | -7 | -25 | -29 | -35 | -49 | -145 | -175 | -203 | -245 | -343 | -725 | -1,015 | -1,225 | -1,421 | -1,715 | -5,075 | -7,105 | -8,575 | -9,947 | -35,525 | -49,735 | -248,675 |
