Q: What are the factor combinations of the number 29,867?

 A:
Positive:   1 x 29867
Negative: -1 x -29867


How do I find the factor combinations of the number 29,867?

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 29,867, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

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 29,867
-1 -29,867

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,867.

Example:
1 x 29,867 = 29,867
and
-1 x -29,867 = 29,867
Notice both answers equal 29,867

With that explanation out of the way, let's continue. Next, we take the number 29,867 and divide it by 2:

29,867 ÷ 2 = 14,933.5

If the quotient is a whole number, then 2 and 14,933.5 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 29,867
-1 -29,867

Now, we try dividing 29,867 by 3:

29,867 ÷ 3 = 9,955.6667

If the quotient is a whole number, then 3 and 9,955.6667 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 29,867
-1 -29,867

Let's try dividing by 4:

29,867 ÷ 4 = 7,466.75

If the quotient is a whole number, then 4 and 7,466.75 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 29,867
-1 29,867
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

129,867
-1-29,867
