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 259,543, 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 | 259,543 | |
-1 | -259,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 259,543.
Example:
1 x 259,543 = 259,543
and
-1 x -259,543 = 259,543
Notice both answers equal 259,543
With that explanation out of the way, let's continue. Next, we take the number 259,543 and divide it by 2:
259,543 ÷ 2 = 129,771.5
If the quotient is a whole number, then 2 and 129,771.5 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 | 259,543 | |
-1 | -259,543 |
Now, we try dividing 259,543 by 3:
259,543 ÷ 3 = 86,514.3333
If the quotient is a whole number, then 3 and 86,514.3333 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 | 259,543 | |
-1 | -259,543 |
Let's try dividing by 4:
259,543 ÷ 4 = 64,885.75
If the quotient is a whole number, then 4 and 64,885.75 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 | 259,543 | |
-1 | 259,543 |
If you did it right, you will end up with this table:
1 | 461 | 563 | 259,543 |
-1 | -461 | -563 | -259,543 |
