How do I find the factor combinations of the number 1,254,337?

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 1,254,337, 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 1,254,337
-1 -1,254,337

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 1,254,337.

Example:
1 x 1,254,337 = 1,254,337
and
-1 x -1,254,337 = 1,254,337
Notice both answers equal 1,254,337

With that explanation out of the way, let's continue. Next, we take the number 1,254,337 and divide it by 2:

1,254,337 ÷ 2 = 627,168.5

If the quotient is a whole number, then 2 and 627,168.5 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 1,254,337
-1 -1,254,337

Now, we try dividing 1,254,337 by 3:

1,254,337 ÷ 3 = 418,112.3333

If the quotient is a whole number, then 3 and 418,112.3333 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 1,254,337
-1 -1,254,337

Let's try dividing by 4:

1,254,337 ÷ 4 = 313,584.25

If the quotient is a whole number, then 4 and 313,584.25 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 1,254,337
-1 1,254,337
Keep dividing by the next highest number until you cannot divide anymore.

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

1729371672032591,0731,1694,8436,1797,51133,90143,253179,1911,254,337
