How do I find the factor combinations of the number 64,006,801?

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 64,006,801, 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 64,006,801
-1 -64,006,801

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 64,006,801.

Example:
1 x 64,006,801 = 64,006,801
and
-1 x -64,006,801 = 64,006,801
Notice both answers equal 64,006,801

With that explanation out of the way, let's continue. Next, we take the number 64,006,801 and divide it by 2:

64,006,801 ÷ 2 = 32,003,400.5

If the quotient is a whole number, then 2 and 32,003,400.5 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 64,006,801
-1 -64,006,801

Now, we try dividing 64,006,801 by 3:

64,006,801 ÷ 3 = 21,335,600.3333

If the quotient is a whole number, then 3 and 21,335,600.3333 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 64,006,801
-1 -64,006,801

Let's try dividing by 4:

64,006,801 ÷ 4 = 16,001,700.25

If the quotient is a whole number, then 4 and 16,001,700.25 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 64,006,801
-1 64,006,801
Keep dividing by the next highest number until you cannot divide anymore.

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

1193,368,77964,006,801
-1-19-3,368,779-64,006,801
