A:
Positive:
1 x 75655 x 151317 x 44585 x 89
Negative:
-1 x -7565-5 x -1513-17 x -445-85 x -89
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 7,565, 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 | 7,565 | |
-1 | -7,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,565.
Example:
1 x 7,565 = 7,565
and
-1 x -7,565 = 7,565
Notice both answers equal 7,565
With that explanation out of the way, let's continue. Next, we take the number 7,565 and divide it by 2:
7,565 ÷ 2 = 3,782.5
If the quotient is a whole number, then 2 and 3,782.5 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 | 7,565 | |
-1 | -7,565 |
Now, we try dividing 7,565 by 3:
7,565 ÷ 3 = 2,521.6667
If the quotient is a whole number, then 3 and 2,521.6667 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 | 7,565 | |
-1 | -7,565 |
Let's try dividing by 4:
7,565 ÷ 4 = 1,891.25
If the quotient is a whole number, then 4 and 1,891.25 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 | 7,565 | |
-1 | 7,565 |
If you did it right, you will end up with this table:
1 | 5 | 17 | 85 | 89 | 445 | 1,513 | 7,565 |
-1 | -5 | -17 | -85 | -89 | -445 | -1,513 | -7,565 |
