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 985,393, 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 | 985,393 | |
-1 | -985,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 985,393.
Example:
1 x 985,393 = 985,393
and
-1 x -985,393 = 985,393
Notice both answers equal 985,393
With that explanation out of the way, let's continue. Next, we take the number 985,393 and divide it by 2:
985,393 ÷ 2 = 492,696.5
If the quotient is a whole number, then 2 and 492,696.5 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 | 985,393 | |
-1 | -985,393 |
Now, we try dividing 985,393 by 3:
985,393 ÷ 3 = 328,464.3333
If the quotient is a whole number, then 3 and 328,464.3333 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 | 985,393 | |
-1 | -985,393 |
Let's try dividing by 4:
985,393 ÷ 4 = 246,348.25
If the quotient is a whole number, then 4 and 246,348.25 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 | 985,393 | |
-1 | 985,393 |
If you did it right, you will end up with this table:
1 | 127 | 7,759 | 985,393 |
-1 | -127 | -7,759 | -985,393 |
