How do I find the factor combinations of the number 124,435,434?

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 124,435,434, 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.

1 124,435,434
-1 -124,435,434

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 124,435,434.

Example:
1 x 124,435,434 = 124,435,434
and
-1 x -124,435,434 = 124,435,434
Notice both answers equal 124,435,434

With that explanation out of the way, let's continue. Next, we take the number 124,435,434 and divide it by 2:

124,435,434 ÷ 2 = 62,217,717

If the quotient is a whole number, then 2 and 62,217,717 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 62,217,717 124,435,434
-1 -2 -62,217,717 -124,435,434

Now, we try dividing 124,435,434 by 3:

124,435,434 ÷ 3 = 41,478,478

If the quotient is a whole number, then 3 and 41,478,478 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 3 41,478,478 62,217,717 124,435,434
-1 -2 -3 -41,478,478 -62,217,717 -124,435,434

Let's try dividing by 4:

124,435,434 ÷ 4 = 31,108,858.5

If the quotient is a whole number, then 4 and 31,108,858.5 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 2 3 41,478,478 62,217,717 124,435,434
-1 -2 -3 -41,478,478 -62,217,717 124,435,434
Keep dividing by the next highest number until you cannot divide anymore.

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