How do I find the factors or divisors of the number 42,789,668?

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 42,789,668, 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 42,789,668

Next, we take the number 42,789,668 and divide it by 2.

In this case, 42,789,668 ÷ 2 = 21,394,834

If the quotient is a whole number, then 2 and 21,394,834 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 21,394,834 42,789,668

Now, we try dividing 42,789,668 by 3.

42,789,668 ÷ 3 = 14,263,222.6667

If the quotient is a whole number, then 3 and 14,263,222.6667 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 21,394,834 42,789,668

Let's try dividing by 4.

42,789,668 ÷ 4 = 10,697,417

If the quotient is a whole number, then 4 and 10,697,417 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 10,697,417 21,394,834 42,789,668

We keep dividing by the next largest number, in this case the number 5. If the quotient of 42,789,668 ÷ 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:

1244919821,96421,78743,57487,14810,697,41721,394,83442,789,668
