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 189,287, 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 | 189,287 | |
-1 | -189,287 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 189,287.
Example:
1 x 189,287 = 189,287
and
-1 x -189,287 = 189,287
Notice both answers equal 189,287
With that explanation out of the way, let's continue. Next, we take the number 189,287 and divide it by 2:
189,287 ÷ 2 = 94,643.5
If the quotient is a whole number, then 2 and 94,643.5 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 | 189,287 | |
-1 | -189,287 |
Now, we try dividing 189,287 by 3:
189,287 ÷ 3 = 63,095.6667
If the quotient is a whole number, then 3 and 63,095.6667 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 | 189,287 | |
-1 | -189,287 |
Let's try dividing by 4:
189,287 ÷ 4 = 47,321.75
If the quotient is a whole number, then 4 and 47,321.75 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 | 189,287 | |
-1 | 189,287 |
If you did it right, you will end up with this table:
1 | 7 | 49 | 3,863 | 27,041 | 189,287 |
-1 | -7 | -49 | -3,863 | -27,041 | -189,287 |
