How do I find the factor combinations of the number 43,013,413?

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 43,013,413, 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 43,013,413
-1 -43,013,413

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 43,013,413.

Example:
1 x 43,013,413 = 43,013,413
and
-1 x -43,013,413 = 43,013,413
Notice both answers equal 43,013,413

With that explanation out of the way, let's continue. Next, we take the number 43,013,413 and divide it by 2:

43,013,413 ÷ 2 = 21,506,706.5

If the quotient is a whole number, then 2 and 21,506,706.5 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 43,013,413
-1 -43,013,413

Now, we try dividing 43,013,413 by 3:

43,013,413 ÷ 3 = 14,337,804.3333

If the quotient is a whole number, then 3 and 14,337,804.3333 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 43,013,413
-1 -43,013,413

Let's try dividing by 4:

43,013,413 ÷ 4 = 10,753,353.25

If the quotient is a whole number, then 4 and 10,753,353.25 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 43,013,413
-1 43,013,413
Keep dividing by the next highest number until you cannot divide anymore.

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

1473172,88714,899135,689915,17943,013,413
