A:
Positive:
1 x 18555 x 3717 x 26535 x 53
Negative:
-1 x -1855-5 x -371-7 x -265-35 x -53
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 1,855, 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 | 1,855 | |
-1 | -1,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,855.
Example:
1 x 1,855 = 1,855
and
-1 x -1,855 = 1,855
Notice both answers equal 1,855
With that explanation out of the way, let's continue. Next, we take the number 1,855 and divide it by 2:
1,855 ÷ 2 = 927.5
If the quotient is a whole number, then 2 and 927.5 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 | 1,855 | |
-1 | -1,855 |
Now, we try dividing 1,855 by 3:
1,855 ÷ 3 = 618.3333
If the quotient is a whole number, then 3 and 618.3333 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 | 1,855 | |
-1 | -1,855 |
Let's try dividing by 4:
1,855 ÷ 4 = 463.75
If the quotient is a whole number, then 4 and 463.75 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 | 1,855 | |
-1 | 1,855 |
If you did it right, you will end up with this table:
1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 |
-1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 |
