How do I find the factor combinations of the number 7,474,901?

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 7,474,901, 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 7,474,901
-1 -7,474,901

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 7,474,901.

Example:
1 x 7,474,901 = 7,474,901
and
-1 x -7,474,901 = 7,474,901
Notice both answers equal 7,474,901

With that explanation out of the way, let's continue. Next, we take the number 7,474,901 and divide it by 2:

7,474,901 ÷ 2 = 3,737,450.5

If the quotient is a whole number, then 2 and 3,737,450.5 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 7,474,901
-1 -7,474,901

Now, we try dividing 7,474,901 by 3:

7,474,901 ÷ 3 = 2,491,633.6667

If the quotient is a whole number, then 3 and 2,491,633.6667 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 7,474,901
-1 -7,474,901

Let's try dividing by 4:

7,474,901 ÷ 4 = 1,868,725.25

If the quotient is a whole number, then 4 and 1,868,725.25 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 7,474,901
-1 7,474,901
Keep dividing by the next highest number until you cannot divide anymore.

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

1749795531,9313,87113,51794,619152,5491,067,8437,474,901
-1-7-49-79-553-1,931-3,871-13,517-94,619-152,549-1,067,843-7,474,901
