1 x 181797 x 259749 x 37153 x 343
Negative:
-1 x -18179-7 x -2597-49 x -371-53 x -343
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 18,179, 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 | 18,179 | |
-1 | -18,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,179.
Example:
1 x 18,179 = 18,179
and
-1 x -18,179 = 18,179
Notice both answers equal 18,179
With that explanation out of the way, let's continue. Next, we take the number 18,179 and divide it by 2:
18,179 ÷ 2 = 9,089.5
If the quotient is a whole number, then 2 and 9,089.5 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 | 18,179 | |
-1 | -18,179 |
Now, we try dividing 18,179 by 3:
18,179 ÷ 3 = 6,059.6667
If the quotient is a whole number, then 3 and 6,059.6667 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 | 18,179 | |
-1 | -18,179 |
Let's try dividing by 4:
18,179 ÷ 4 = 4,544.75
If the quotient is a whole number, then 4 and 4,544.75 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 | 18,179 | |
-1 | 18,179 |
If you did it right, you will end up with this table:
1 | 7 | 49 | 53 | 343 | 371 | 2,597 | 18,179 |
-1 | -7 | -49 | -53 | -343 | -371 | -2,597 | -18,179 |
