1 x 659655 x 1319379 x 835167 x 395
Negative:
-1 x -65965-5 x -13193-79 x -835-167 x -395
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 65,965, 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 | 65,965 | |
-1 | -65,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,965.
Example:
1 x 65,965 = 65,965
and
-1 x -65,965 = 65,965
Notice both answers equal 65,965
With that explanation out of the way, let's continue. Next, we take the number 65,965 and divide it by 2:
65,965 ÷ 2 = 32,982.5
If the quotient is a whole number, then 2 and 32,982.5 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 | 65,965 | |
-1 | -65,965 |
Now, we try dividing 65,965 by 3:
65,965 ÷ 3 = 21,988.3333
If the quotient is a whole number, then 3 and 21,988.3333 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 | 65,965 | |
-1 | -65,965 |
Let's try dividing by 4:
65,965 ÷ 4 = 16,491.25
If the quotient is a whole number, then 4 and 16,491.25 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 | 65,965 | |
-1 | 65,965 |
If you did it right, you will end up with this table:
1 | 5 | 79 | 167 | 395 | 835 | 13,193 | 65,965 |
-1 | -5 | -79 | -167 | -395 | -835 | -13,193 | -65,965 |
