How do I find the factor combinations of the number 17,031,677?

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 17,031,677, 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 17,031,677
-1 -17,031,677

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 17,031,677.

Example:
1 x 17,031,677 = 17,031,677
and
-1 x -17,031,677 = 17,031,677
Notice both answers equal 17,031,677

With that explanation out of the way, let's continue. Next, we take the number 17,031,677 and divide it by 2:

17,031,677 ÷ 2 = 8,515,838.5

If the quotient is a whole number, then 2 and 8,515,838.5 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 17,031,677
-1 -17,031,677

Now, we try dividing 17,031,677 by 3:

17,031,677 ÷ 3 = 5,677,225.6667

If the quotient is a whole number, then 3 and 5,677,225.6667 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 17,031,677
-1 -17,031,677

Let's try dividing by 4:

17,031,677 ÷ 4 = 4,257,919.25

If the quotient is a whole number, then 4 and 4,257,919.25 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 17,031,677
-1 17,031,677
Keep dividing by the next highest number until you cannot divide anymore.

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

1131732,2497,57398,4491,310,12917,031,677
-1-13-173-2,249-7,573-98,449-1,310,129-17,031,677
