How do I find the factor combinations of the number 5,722,787?

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 5,722,787, 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 5,722,787
-1 -5,722,787

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 5,722,787.

Example:
1 x 5,722,787 = 5,722,787
and
-1 x -5,722,787 = 5,722,787
Notice both answers equal 5,722,787

With that explanation out of the way, let's continue. Next, we take the number 5,722,787 and divide it by 2:

5,722,787 ÷ 2 = 2,861,393.5

If the quotient is a whole number, then 2 and 2,861,393.5 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 5,722,787
-1 -5,722,787

Now, we try dividing 5,722,787 by 3:

5,722,787 ÷ 3 = 1,907,595.6667

If the quotient is a whole number, then 3 and 1,907,595.6667 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 5,722,787
-1 -5,722,787

Let's try dividing by 4:

5,722,787 ÷ 4 = 1,430,696.75

If the quotient is a whole number, then 4 and 1,430,696.75 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 5,722,787
-1 5,722,787
Keep dividing by the next highest number until you cannot divide anymore.

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

173072,1492,66318,641817,5415,722,787
-1-7-307-2,149-2,663-18,641-817,541-5,722,787
