How do I find the factors or divisors of the number 25,420?

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 25,420, 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 25,420

Next, we take the number 25,420 and divide it by 2.

In this case, 25,420 ÷ 2 = 12,710

If the quotient is a whole number, then 2 and 12,710 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 12,710 25,420

Now, we try dividing 25,420 by 3.

25,420 ÷ 3 = 8,473.3333

If the quotient is a whole number, then 3 and 8,473.3333 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 12,710 25,420

Let's try dividing by 4.

25,420 ÷ 4 = 6,355

If the quotient is a whole number, then 4 and 6,355 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 6,355 12,710 25,420

We keep dividing by the next largest number, in this case the number 5. If the quotient of 25,420 ÷ 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:

12451020314162821241551642053104106208201,2712,5425,0846,35512,71025,420

All of the numbers in the table above can be evenly divided into the number 25,420.

Finally, for your reference, here are all of the divisor combinations of the number 25,420:

1 x 254202 x 127104 x 63555 x 508410 x 254220 x 127131 x 82041 x 62062 x 41082 x 310124 x 205155 x 164
