How do I find the factor combinations of the number 150,803?

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 150,803, 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.

1 150,803
-1 -150,803

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 150,803.

Example:
1 x 150,803 = 150,803
and
-1 x -150,803 = 150,803
Notice both answers equal 150,803

With that explanation out of the way, let's continue. Next, we take the number 150,803 and divide it by 2:

150,803 ÷ 2 = 75,401.5

If the quotient is a whole number, then 2 and 75,401.5 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:

1 150,803
-1 -150,803

Now, we try dividing 150,803 by 3:

150,803 ÷ 3 = 50,267.6667

If the quotient is a whole number, then 3 and 50,267.6667 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:

1 150,803
-1 -150,803

Let's try dividing by 4:

150,803 ÷ 4 = 37,700.75

If the quotient is a whole number, then 4 and 37,700.75 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:

1 150,803
-1 150,803
Keep dividing by the next highest number until you cannot divide anymore.

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

1197,937150,803
-1-19-7,937-150,803
