How do I find the factor combinations of the number 73,751,635?

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 73,751,635, 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 73,751,635
-1 -73,751,635

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 73,751,635.

Example:
1 x 73,751,635 = 73,751,635
and
-1 x -73,751,635 = 73,751,635
Notice both answers equal 73,751,635

With that explanation out of the way, let's continue. Next, we take the number 73,751,635 and divide it by 2:

73,751,635 ÷ 2 = 36,875,817.5

If the quotient is a whole number, then 2 and 36,875,817.5 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 73,751,635
-1 -73,751,635

Now, we try dividing 73,751,635 by 3:

73,751,635 ÷ 3 = 24,583,878.3333

If the quotient is a whole number, then 3 and 24,583,878.3333 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 73,751,635
-1 -73,751,635

Let's try dividing by 4:

73,751,635 ÷ 4 = 18,437,908.75

If the quotient is a whole number, then 4 and 18,437,908.75 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 73,751,635
-1 73,751,635
Keep dividing by the next highest number until you cannot divide anymore.

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