How do I find the factor combinations of the number 45,734,015?

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 45,734,015, 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 45,734,015
-1 -45,734,015

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 45,734,015.

Example:
1 x 45,734,015 = 45,734,015
and
-1 x -45,734,015 = 45,734,015
Notice both answers equal 45,734,015

With that explanation out of the way, let's continue. Next, we take the number 45,734,015 and divide it by 2:

45,734,015 ÷ 2 = 22,867,007.5

If the quotient is a whole number, then 2 and 22,867,007.5 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 45,734,015
-1 -45,734,015

Now, we try dividing 45,734,015 by 3:

45,734,015 ÷ 3 = 15,244,671.6667

If the quotient is a whole number, then 3 and 15,244,671.6667 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 45,734,015
-1 -45,734,015

Let's try dividing by 4:

45,734,015 ÷ 4 = 11,433,503.75

If the quotient is a whole number, then 4 and 11,433,503.75 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 45,734,015
-1 45,734,015
Keep dividing by the next highest number until you cannot divide anymore.

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

1529145315,4071,577,0359,146,80345,734,015
-1-5-29-145-315,407-1,577,035-9,146,803-45,734,015
