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 570,785, 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 | 570,785 | |
-1 | -570,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 570,785.
Example:
1 x 570,785 = 570,785
and
-1 x -570,785 = 570,785
Notice both answers equal 570,785
With that explanation out of the way, let's continue. Next, we take the number 570,785 and divide it by 2:
570,785 ÷ 2 = 285,392.5
If the quotient is a whole number, then 2 and 285,392.5 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 | 570,785 | |
-1 | -570,785 |
Now, we try dividing 570,785 by 3:
570,785 ÷ 3 = 190,261.6667
If the quotient is a whole number, then 3 and 190,261.6667 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 | 570,785 | |
-1 | -570,785 |
Let's try dividing by 4:
570,785 ÷ 4 = 142,696.25
If the quotient is a whole number, then 4 and 142,696.25 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 | 570,785 | |
-1 | 570,785 |
If you did it right, you will end up with this table:
1 | 5 | 114,157 | 570,785 |
-1 | -5 | -114,157 | -570,785 |
