How do I find the factor combinations of the number 536,226,431?

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 536,226,431, 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.

1 536,226,431
-1 -536,226,431

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 536,226,431.

Example:
1 x 536,226,431 = 536,226,431
and
-1 x -536,226,431 = 536,226,431
Notice both answers equal 536,226,431

With that explanation out of the way, let's continue. Next, we take the number 536,226,431 and divide it by 2:

536,226,431 ÷ 2 = 268,113,215.5

If the quotient is a whole number, then 2 and 268,113,215.5 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:

1 536,226,431
-1 -536,226,431

Now, we try dividing 536,226,431 by 3:

536,226,431 ÷ 3 = 178,742,143.6667

If the quotient is a whole number, then 3 and 178,742,143.6667 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:

1 536,226,431
-1 -536,226,431

Let's try dividing by 4:

536,226,431 ÷ 4 = 134,056,607.75

If the quotient is a whole number, then 4 and 134,056,607.75 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:

1 536,226,431
-1 536,226,431
Keep dividing by the next highest number until you cannot divide anymore.

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

11347611877,62111,409,07341,248,187536,226,431
