How do I find the factor combinations of the number 23,375,263?

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 23,375,263, 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 23,375,263
-1 -23,375,263

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 23,375,263.

Example:
1 x 23,375,263 = 23,375,263
and
-1 x -23,375,263 = 23,375,263
Notice both answers equal 23,375,263

With that explanation out of the way, let's continue. Next, we take the number 23,375,263 and divide it by 2:

23,375,263 ÷ 2 = 11,687,631.5

If the quotient is a whole number, then 2 and 11,687,631.5 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 23,375,263
-1 -23,375,263

Now, we try dividing 23,375,263 by 3:

23,375,263 ÷ 3 = 7,791,754.3333

If the quotient is a whole number, then 3 and 7,791,754.3333 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 23,375,263
-1 -23,375,263

Let's try dividing by 4:

23,375,263 ÷ 4 = 5,843,815.75

If the quotient is a whole number, then 4 and 5,843,815.75 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 23,375,263
-1 23,375,263
Keep dividing by the next highest number until you cannot divide anymore.

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

1193173,8816,02373,7391,230,27723,375,263
