How do I find the factor combinations of the number 310,653,343?

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 310,653,343, 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.

1 310,653,343
-1 -310,653,343

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 310,653,343.

Example:
1 x 310,653,343 = 310,653,343
and
-1 x -310,653,343 = 310,653,343
Notice both answers equal 310,653,343

With that explanation out of the way, let's continue. Next, we take the number 310,653,343 and divide it by 2:

310,653,343 ÷ 2 = 155,326,671.5

If the quotient is a whole number, then 2 and 155,326,671.5 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:

1 310,653,343
-1 -310,653,343

Now, we try dividing 310,653,343 by 3:

310,653,343 ÷ 3 = 103,551,114.3333

If the quotient is a whole number, then 3 and 103,551,114.3333 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:

1 310,653,343
-1 -310,653,343

Let's try dividing by 4:

310,653,343 ÷ 4 = 77,663,335.75

If the quotient is a whole number, then 4 and 77,663,335.75 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:

1 310,653,343
-1 310,653,343
Keep dividing by the next highest number until you cannot divide anymore.

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

1711137789911211433176238479791,0011,1571,5732,2193,4874,1216,8538,09910,76911,01112,72724,40928,21328,84738,35745,33175,38389,089139,997197,491268,499310,343317,317366,769498,641979,9792,172,4012,567,3833,413,7733,490,4874,034,45923,896,41128,241,21344,379,049310,653,343
