How do I find the factor combinations of the number 5,637,203?

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 5,637,203, 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 5,637,203
-1 -5,637,203

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 5,637,203.

Example:
1 x 5,637,203 = 5,637,203
and
-1 x -5,637,203 = 5,637,203
Notice both answers equal 5,637,203

With that explanation out of the way, let's continue. Next, we take the number 5,637,203 and divide it by 2:

5,637,203 ÷ 2 = 2,818,601.5

If the quotient is a whole number, then 2 and 2,818,601.5 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 5,637,203
-1 -5,637,203

Now, we try dividing 5,637,203 by 3:

5,637,203 ÷ 3 = 1,879,067.6667

If the quotient is a whole number, then 3 and 1,879,067.6667 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 5,637,203
-1 -5,637,203

Let's try dividing by 4:

5,637,203 ÷ 4 = 1,409,300.75

If the quotient is a whole number, then 4 and 1,409,300.75 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 5,637,203
-1 5,637,203
Keep dividing by the next highest number until you cannot divide anymore.

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

11113791434998691,0275,4896,48711,29739,42171,357433,631512,4735,637,203
