How do I find the factor combinations of the number 142,885?

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 142,885, 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.

1 142,885
-1 -142,885

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 142,885.

Example:
1 x 142,885 = 142,885
and
-1 x -142,885 = 142,885
Notice both answers equal 142,885

With that explanation out of the way, let's continue. Next, we take the number 142,885 and divide it by 2:

142,885 ÷ 2 = 71,442.5

If the quotient is a whole number, then 2 and 71,442.5 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:

1 142,885
-1 -142,885

Now, we try dividing 142,885 by 3:

142,885 ÷ 3 = 47,628.3333

If the quotient is a whole number, then 3 and 47,628.3333 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:

1 142,885
-1 -142,885

Let's try dividing by 4:

142,885 ÷ 4 = 35,721.25

If the quotient is a whole number, then 4 and 35,721.25 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:

1 142,885
-1 142,885
Keep dividing by the next highest number until you cannot divide anymore.

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

151741852056971,6813,4858,40528,577142,885
-1-5-17-41-85-205-697-1,681-3,485-8,405-28,577-142,885
