How do I find the factor combinations of the number 40,001,190?

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 40,001,190, 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 40,001,190
-1 -40,001,190

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 40,001,190.

Example:
1 x 40,001,190 = 40,001,190
and
-1 x -40,001,190 = 40,001,190
Notice both answers equal 40,001,190

With that explanation out of the way, let's continue. Next, we take the number 40,001,190 and divide it by 2:

40,001,190 ÷ 2 = 20,000,595

If the quotient is a whole number, then 2 and 20,000,595 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 20,000,595 40,001,190
-1 -2 -20,000,595 -40,001,190

Now, we try dividing 40,001,190 by 3:

40,001,190 ÷ 3 = 13,333,730

If the quotient is a whole number, then 3 and 13,333,730 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 13,333,730 20,000,595 40,001,190
-1 -2 -3 -13,333,730 -20,000,595 -40,001,190

Let's try dividing by 4:

40,001,190 ÷ 4 = 10,000,297.5

If the quotient is a whole number, then 4 and 10,000,297.5 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 13,333,730 20,000,595 40,001,190
-1 -2 -3 -13,333,730 -20,000,595 40,001,190
Keep dividing by the next highest number until you cannot divide anymore.

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