How do I find the factor combinations of the number 57,036,679?

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 divisors of larger numbers. To find the factor combinations of the number 57,036,679, it is easier to work with a table - it's called factoring from the outside in.

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. Then, below that, write the numbers as a negative as well.

1 57,036,679
-1 -57,036,679

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,036,679.

Example:
1 x 57,036,679 = 57,036,679
and
-1 x -57,036,679 = 57,036,679
Notice both answers equal 57,036,679

With that explanation out of the way, let's continue. Next, we take the number 57,036,679 and divide it by 2:

57,036,679 ÷ 2 = 28,518,339.5

If the quotient is a whole number, then 2 and 28,518,339.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 57,036,679
-1 -57,036,679

Now, we try dividing 57,036,679 by 3:

57,036,679 ÷ 3 = 19,012,226.3333

If the quotient is a whole number, then 3 and 19,012,226.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 57,036,679
-1 -57,036,679

Let's try dividing by 4:

57,036,679 ÷ 4 = 14,259,169.75

If the quotient is a whole number, then 4 and 14,259,169.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 57,036,679
-1 57,036,679
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

17971675036791,1693,52116,19948,79184,001113,393341,537588,0078,148,09757,036,679
