How do I find the factor combinations of the number 1,336,685?

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 1,336,685, 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 1,336,685
-1 -1,336,685

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 1,336,685.

Example:
1 x 1,336,685 = 1,336,685
and
-1 x -1,336,685 = 1,336,685
Notice both answers equal 1,336,685

With that explanation out of the way, let's continue. Next, we take the number 1,336,685 and divide it by 2:

1,336,685 ÷ 2 = 668,342.5

If the quotient is a whole number, then 2 and 668,342.5 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 1,336,685
-1 -1,336,685

Now, we try dividing 1,336,685 by 3:

1,336,685 ÷ 3 = 445,561.6667

If the quotient is a whole number, then 3 and 445,561.6667 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 1,336,685
-1 -1,336,685

Let's try dividing by 4:

1,336,685 ÷ 4 = 334,171.25

If the quotient is a whole number, then 4 and 334,171.25 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 1,336,685
-1 1,336,685
Keep dividing by the next highest number until you cannot divide anymore.

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

157351812119051,0551,2671,4776,3357,38538,191190,955267,3371,336,685
