How do I find the factor combinations of the number 58,508,155?

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 58,508,155, 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 58,508,155
-1 -58,508,155

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 58,508,155.

Example:
1 x 58,508,155 = 58,508,155
and
-1 x -58,508,155 = 58,508,155
Notice both answers equal 58,508,155

With that explanation out of the way, let's continue. Next, we take the number 58,508,155 and divide it by 2:

58,508,155 ÷ 2 = 29,254,077.5

If the quotient is a whole number, then 2 and 29,254,077.5 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 58,508,155
-1 -58,508,155

Now, we try dividing 58,508,155 by 3:

58,508,155 ÷ 3 = 19,502,718.3333

If the quotient is a whole number, then 3 and 19,502,718.3333 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 58,508,155
-1 -58,508,155

Let's try dividing by 4:

58,508,155 ÷ 4 = 14,627,038.75

If the quotient is a whole number, then 4 and 14,627,038.75 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 58,508,155
-1 58,508,155
Keep dividing by the next highest number until you cannot divide anymore.

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

1589445131,479657,39511,701,63158,508,155
-1-5-89-445-131,479-657,395-11,701,631-58,508,155
