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 521,629, 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 | 521,629 | |
-1 | -521,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 521,629.
Example:
1 x 521,629 = 521,629
and
-1 x -521,629 = 521,629
Notice both answers equal 521,629
With that explanation out of the way, let's continue. Next, we take the number 521,629 and divide it by 2:
521,629 ÷ 2 = 260,814.5
If the quotient is a whole number, then 2 and 260,814.5 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 | 521,629 | |
-1 | -521,629 |
Now, we try dividing 521,629 by 3:
521,629 ÷ 3 = 173,876.3333
If the quotient is a whole number, then 3 and 173,876.3333 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 | 521,629 | |
-1 | -521,629 |
Let's try dividing by 4:
521,629 ÷ 4 = 130,407.25
If the quotient is a whole number, then 4 and 130,407.25 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 | 521,629 | |
-1 | 521,629 |
If you did it right, you will end up with this table:
1 | 89 | 5,861 | 521,629 |
-1 | -89 | -5,861 | -521,629 |
