How do I find the factor combinations of the number 26,537,917?

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 26,537,917, 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 26,537,917
-1 -26,537,917

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 26,537,917.

Example:
1 x 26,537,917 = 26,537,917
and
-1 x -26,537,917 = 26,537,917
Notice both answers equal 26,537,917

With that explanation out of the way, let's continue. Next, we take the number 26,537,917 and divide it by 2:

26,537,917 ÷ 2 = 13,268,958.5

If the quotient is a whole number, then 2 and 13,268,958.5 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 26,537,917
-1 -26,537,917

Now, we try dividing 26,537,917 by 3:

26,537,917 ÷ 3 = 8,845,972.3333

If the quotient is a whole number, then 3 and 8,845,972.3333 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 26,537,917
-1 -26,537,917

Let's try dividing by 4:

26,537,917 ÷ 4 = 6,634,479.25

If the quotient is a whole number, then 4 and 6,634,479.25 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 26,537,917
-1 26,537,917
Keep dividing by the next highest number until you cannot divide anymore.

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

1737792595531,2972,9239,07920,46147,989102,463335,923717,2413,791,13126,537,917
