How do I find the factor combinations of the number 5,321,935?

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 5,321,935, 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 5,321,935
-1 -5,321,935

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 5,321,935.

Example:
1 x 5,321,935 = 5,321,935
and
-1 x -5,321,935 = 5,321,935
Notice both answers equal 5,321,935

With that explanation out of the way, let's continue. Next, we take the number 5,321,935 and divide it by 2:

5,321,935 ÷ 2 = 2,660,967.5

If the quotient is a whole number, then 2 and 2,660,967.5 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 5,321,935
-1 -5,321,935

Now, we try dividing 5,321,935 by 3:

5,321,935 ÷ 3 = 1,773,978.3333

If the quotient is a whole number, then 3 and 1,773,978.3333 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 5,321,935
-1 -5,321,935

Let's try dividing by 4:

5,321,935 ÷ 4 = 1,330,483.75

If the quotient is a whole number, then 4 and 1,330,483.75 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 5,321,935
-1 5,321,935
Keep dividing by the next highest number until you cannot divide anymore.

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

151729851271452894936351,4452,1592,4653,6838,38110,79518,41536,70341,90562,611183,515313,0551,064,3875,321,935
