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 564,451, 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 | 564,451 | |
-1 | -564,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 564,451.
Example:
1 x 564,451 = 564,451
and
-1 x -564,451 = 564,451
Notice both answers equal 564,451
With that explanation out of the way, let's continue. Next, we take the number 564,451 and divide it by 2:
564,451 ÷ 2 = 282,225.5
If the quotient is a whole number, then 2 and 282,225.5 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 | 564,451 | |
-1 | -564,451 |
Now, we try dividing 564,451 by 3:
564,451 ÷ 3 = 188,150.3333
If the quotient is a whole number, then 3 and 188,150.3333 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 | 564,451 | |
-1 | -564,451 |
Let's try dividing by 4:
564,451 ÷ 4 = 141,112.75
If the quotient is a whole number, then 4 and 141,112.75 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 | 564,451 | |
-1 | 564,451 |
If you did it right, you will end up with this table:
1 | 17 | 33,203 | 564,451 |
-1 | -17 | -33,203 | -564,451 |
