How do I find the factor combinations of the number 743,422,508?

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 743,422,508, 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.

1 743,422,508
-1 -743,422,508

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 743,422,508.

Example:
1 x 743,422,508 = 743,422,508
and
-1 x -743,422,508 = 743,422,508
Notice both answers equal 743,422,508

With that explanation out of the way, let's continue. Next, we take the number 743,422,508 and divide it by 2:

743,422,508 ÷ 2 = 371,711,254

If the quotient is a whole number, then 2 and 371,711,254 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 371,711,254 743,422,508
-1 -2 -371,711,254 -743,422,508

Now, we try dividing 743,422,508 by 3:

743,422,508 ÷ 3 = 247,807,502.6667

If the quotient is a whole number, then 3 and 247,807,502.6667 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 2 371,711,254 743,422,508
-1 -2 -371,711,254 -743,422,508

Let's try dividing by 4:

743,422,508 ÷ 4 = 185,855,627

If the quotient is a whole number, then 4 and 185,855,627 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 4 185,855,627 371,711,254 743,422,508
-1 -2 -4 -185,855,627 -371,711,254 743,422,508
Keep dividing by the next highest number until you cannot divide anymore.

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

124185,855,627371,711,254743,422,508
-1-2-4-185,855,627-371,711,254-743,422,508
