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 73,043,065, it is easier to work with a table - it's called factoring from the outside in.
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 | 73,043,065 | |
| -1 | -73,043,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,043,065.
Example:
1 x 73,043,065 = 73,043,065
and
-1 x -73,043,065 = 73,043,065
Notice both answers equal 73,043,065
With that explanation out of the way, let's continue. Next, we take the number 73,043,065 and divide it by 2:
73,043,065 ÷ 2 = 36,521,532.5
If the quotient is a whole number, then 2 and 36,521,532.5 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 | 73,043,065 | |
| -1 | -73,043,065 |
Now, we try dividing 73,043,065 by 3:
73,043,065 ÷ 3 = 24,347,688.3333
If the quotient is a whole number, then 3 and 24,347,688.3333 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 | 73,043,065 | |
| -1 | -73,043,065 |
Let's try dividing by 4:
73,043,065 ÷ 4 = 18,260,766.25
If the quotient is a whole number, then 4 and 18,260,766.25 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 | 73,043,065 | |
| -1 | 73,043,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 335 | 337 | 647 | 1,685 | 3,235 | 22,579 | 43,349 | 112,895 | 216,745 | 218,039 | 1,090,195 | 14,608,613 | 73,043,065 |
| -1 | -5 | -67 | -335 | -337 | -647 | -1,685 | -3,235 | -22,579 | -43,349 | -112,895 | -216,745 | -218,039 | -1,090,195 | -14,608,613 | -73,043,065 |
