How do I find the factors or divisors of the number 150,525,540?

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 150,525,540, 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.

1 150,525,540

Next, we take the number 150,525,540 and divide it by 2.

In this case, 150,525,540 ÷ 2 = 75,262,770

If the quotient is a whole number, then 2 and 75,262,770 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 75,262,770 150,525,540

Now, we try dividing 150,525,540 by 3.

150,525,540 ÷ 3 = 50,175,180

If the quotient is a whole number, then 3 and 50,175,180 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 3 50,175,180 75,262,770 150,525,540

Let's try dividing by 4.

150,525,540 ÷ 4 = 37,631,385

If the quotient is a whole number, then 4 and 37,631,385 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 3 4 37,631,385 50,175,180 75,262,770 150,525,540

We keep dividing by the next largest number, in this case the number 5. If the quotient of 150,525,540 ÷ 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:
