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 890,779, 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 | 890,779 | |
-1 | -890,779 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 890,779.
Example:
1 x 890,779 = 890,779
and
-1 x -890,779 = 890,779
Notice both answers equal 890,779
With that explanation out of the way, let's continue. Next, we take the number 890,779 and divide it by 2:
890,779 ÷ 2 = 445,389.5
If the quotient is a whole number, then 2 and 445,389.5 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 | 890,779 | |
-1 | -890,779 |
Now, we try dividing 890,779 by 3:
890,779 ÷ 3 = 296,926.3333
If the quotient is a whole number, then 3 and 296,926.3333 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 | 890,779 | |
-1 | -890,779 |
Let's try dividing by 4:
890,779 ÷ 4 = 222,694.75
If the quotient is a whole number, then 4 and 222,694.75 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 | 890,779 | |
-1 | 890,779 |
If you did it right, you will end up with this table:
1 | 113 | 7,883 | 890,779 |
-1 | -113 | -7,883 | -890,779 |
