Q: What are the factors or divisors of the number 145,128?

How do I find the factors or divisors of the number 145,128?

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 145,128, 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

145,128

Next, we take the number 145,128 and divide it by 2.

In this case, 145,128 ÷ 2 = 72,564

If the quotient is a whole number, then 2 and 72,564 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Now, we try dividing 145,128 by 3.

145,128 ÷ 3 = 48,376

If the quotient is a whole number, then 3 and 48,376 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:

Let's try dividing by 4.

145,128 ÷ 4 = 36,282

If the quotient is a whole number, then 4 and 36,282 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:

We keep dividing by the next largest number, in this case the number 5. If the quotient of 145,128 ÷ 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:

All of the numbers in the table above can be evenly divided into the number 145,128.

Finally, for your reference, here are all of the divisor combinations of the number 145,128:

1 x 1451282 x 725643 x 483764 x 362826 x 241888 x 1814112 x 1209424 x 6047
