How do I find the factor combinations of the number 142,005,556?

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 142,005,556, 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.

1 142,005,556
-1 -142,005,556

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 142,005,556.

Example:
1 x 142,005,556 = 142,005,556
and
-1 x -142,005,556 = 142,005,556
Notice both answers equal 142,005,556

With that explanation out of the way, let's continue. Next, we take the number 142,005,556 and divide it by 2:

142,005,556 ÷ 2 = 71,002,778

If the quotient is a whole number, then 2 and 71,002,778 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 71,002,778 142,005,556
-1 -2 -71,002,778 -142,005,556

Now, we try dividing 142,005,556 by 3:

142,005,556 ÷ 3 = 47,335,185.3333

If the quotient is a whole number, then 3 and 47,335,185.3333 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 71,002,778 142,005,556
-1 -2 -71,002,778 -142,005,556

Let's try dividing by 4:

142,005,556 ÷ 4 = 35,501,389

If the quotient is a whole number, then 4 and 35,501,389 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 35,501,389 71,002,778 142,005,556
-1 -2 -4 -35,501,389 -71,002,778 142,005,556
Keep dividing by the next highest number until you cannot divide anymore.

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