How do I find the factor combinations of the number 53,375,801?

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 53,375,801, 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 53,375,801
-1 -53,375,801

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 53,375,801.

Example:
1 x 53,375,801 = 53,375,801
and
-1 x -53,375,801 = 53,375,801
Notice both answers equal 53,375,801

With that explanation out of the way, let's continue. Next, we take the number 53,375,801 and divide it by 2:

53,375,801 ÷ 2 = 26,687,900.5

If the quotient is a whole number, then 2 and 26,687,900.5 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 53,375,801
-1 -53,375,801

Now, we try dividing 53,375,801 by 3:

53,375,801 ÷ 3 = 17,791,933.6667

If the quotient is a whole number, then 3 and 17,791,933.6667 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 53,375,801
-1 -53,375,801

Let's try dividing by 4:

53,375,801 ÷ 4 = 13,343,950.25

If the quotient is a whole number, then 4 and 13,343,950.25 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 53,375,801
-1 53,375,801
Keep dividing by the next highest number until you cannot divide anymore.

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

11723391136,5112,320,6873,139,75353,375,801
-1-17-23-391-136,511-2,320,687-3,139,753-53,375,801
