How do I find the factor combinations of the number 290,069?

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 290,069, 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.

1 290,069
-1 -290,069

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 290,069.

Example:
1 x 290,069 = 290,069
and
-1 x -290,069 = 290,069
Notice both answers equal 290,069

With that explanation out of the way, let's continue. Next, we take the number 290,069 and divide it by 2:

290,069 ÷ 2 = 145,034.5

If the quotient is a whole number, then 2 and 145,034.5 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:

1 290,069
-1 -290,069

Now, we try dividing 290,069 by 3:

290,069 ÷ 3 = 96,689.6667

If the quotient is a whole number, then 3 and 96,689.6667 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:

1 290,069
-1 -290,069

Let's try dividing by 4:

290,069 ÷ 4 = 72,517.25

If the quotient is a whole number, then 4 and 72,517.25 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:

1 290,069
-1 290,069
Keep dividing by the next highest number until you cannot divide anymore.

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

113534216895,47322,313290,069
-1-13-53-421-689-5,473-22,313-290,069
