How do I find the factors or divisors of the number 168,655,940?

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 factors of larger numbers. To find the factors of the number 168,655,940, it is easiest to start from the outside in. Here's what we mean:

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.

1 168,655,940

Next, we take the number 168,655,940 and divide it by 2.

In this case, 168,655,940 ÷ 2 = 84,327,970

If the quotient is a whole number, then 2 and 84,327,970 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 84,327,970 168,655,940

Now, we try dividing 168,655,940 by 3.

168,655,940 ÷ 3 = 56,218,646.6667

If the quotient is a whole number, then 3 and 56,218,646.6667 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 84,327,970 168,655,940

Let's try dividing by 4.

168,655,940 ÷ 4 = 42,163,985

If the quotient is a whole number, then 4 and 42,163,985 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 4 42,163,985 84,327,970 168,655,940

We keep dividing by the next largest number, in this case the number 5. If the quotient of 168,655,940 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:
