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 189,787, 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 | 189,787 | |
-1 | -189,787 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 189,787.
Example:
1 x 189,787 = 189,787
and
-1 x -189,787 = 189,787
Notice both answers equal 189,787
With that explanation out of the way, let's continue. Next, we take the number 189,787 and divide it by 2:
189,787 ÷ 2 = 94,893.5
If the quotient is a whole number, then 2 and 94,893.5 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 | 189,787 | |
-1 | -189,787 |
Now, we try dividing 189,787 by 3:
189,787 ÷ 3 = 63,262.3333
If the quotient is a whole number, then 3 and 63,262.3333 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 | 189,787 | |
-1 | -189,787 |
Let's try dividing by 4:
189,787 ÷ 4 = 47,446.75
If the quotient is a whole number, then 4 and 47,446.75 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 | 189,787 | |
-1 | 189,787 |
If you did it right, you will end up with this table:
1 | 13 | 169 | 1,123 | 14,599 | 189,787 |
-1 | -13 | -169 | -1,123 | -14,599 | -189,787 |
