How do I find the factor combinations of the number 2,942,597?

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 2,942,597, 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 2,942,597
-1 -2,942,597

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 2,942,597.

Example:
1 x 2,942,597 = 2,942,597
and
-1 x -2,942,597 = 2,942,597
Notice both answers equal 2,942,597

With that explanation out of the way, let's continue. Next, we take the number 2,942,597 and divide it by 2:

2,942,597 ÷ 2 = 1,471,298.5

If the quotient is a whole number, then 2 and 1,471,298.5 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 2,942,597
-1 -2,942,597

Now, we try dividing 2,942,597 by 3:

2,942,597 ÷ 3 = 980,865.6667

If the quotient is a whole number, then 3 and 980,865.6667 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 2,942,597
-1 -2,942,597

Let's try dividing by 4:

2,942,597 ÷ 4 = 735,649.25

If the quotient is a whole number, then 4 and 735,649.25 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 2,942,597
-1 2,942,597
Keep dividing by the next highest number until you cannot divide anymore.

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

1723491613433731,1272,6117,8898,57918,27760,053127,939420,3712,942,597
