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 939,289, 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 | 939,289 | |
-1 | -939,289 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 939,289.
Example:
1 x 939,289 = 939,289
and
-1 x -939,289 = 939,289
Notice both answers equal 939,289
With that explanation out of the way, let's continue. Next, we take the number 939,289 and divide it by 2:
939,289 ÷ 2 = 469,644.5
If the quotient is a whole number, then 2 and 469,644.5 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 | 939,289 | |
-1 | -939,289 |
Now, we try dividing 939,289 by 3:
939,289 ÷ 3 = 313,096.3333
If the quotient is a whole number, then 3 and 313,096.3333 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 | 939,289 | |
-1 | -939,289 |
Let's try dividing by 4:
939,289 ÷ 4 = 234,822.25
If the quotient is a whole number, then 4 and 234,822.25 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 | 939,289 | |
-1 | 939,289 |
If you did it right, you will end up with this table:
1 | 13 | 72,253 | 939,289 |
-1 | -13 | -72,253 | -939,289 |
