How do I find the factor combinations of the number 774,449?

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 774,449, 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.

1 774,449
-1 -774,449

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 774,449.

Example:
1 x 774,449 = 774,449
and
-1 x -774,449 = 774,449
Notice both answers equal 774,449

With that explanation out of the way, let's continue. Next, we take the number 774,449 and divide it by 2:

774,449 ÷ 2 = 387,224.5

If the quotient is a whole number, then 2 and 387,224.5 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:

1 774,449
-1 -774,449

Now, we try dividing 774,449 by 3:

774,449 ÷ 3 = 258,149.6667

If the quotient is a whole number, then 3 and 258,149.6667 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:

1 774,449
-1 -774,449

Let's try dividing by 4:

774,449 ÷ 4 = 193,612.25

If the quotient is a whole number, then 4 and 193,612.25 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:

1 774,449
-1 774,449
Keep dividing by the next highest number until you cannot divide anymore.

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

113415331,45318,88959,573774,449
-1-13-41-533-1,453-18,889-59,573-774,449
