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 72,703,595, 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 | 72,703,595 | |
| -1 | -72,703,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 72,703,595.
Example:
1 x 72,703,595 = 72,703,595
and
-1 x -72,703,595 = 72,703,595
Notice both answers equal 72,703,595
With that explanation out of the way, let's continue. Next, we take the number 72,703,595 and divide it by 2:
72,703,595 ÷ 2 = 36,351,797.5
If the quotient is a whole number, then 2 and 36,351,797.5 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 | 72,703,595 | |
| -1 | -72,703,595 |
Now, we try dividing 72,703,595 by 3:
72,703,595 ÷ 3 = 24,234,531.6667
If the quotient is a whole number, then 3 and 24,234,531.6667 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 | 72,703,595 | |
| -1 | -72,703,595 |
Let's try dividing by 4:
72,703,595 ÷ 4 = 18,175,898.75
If the quotient is a whole number, then 4 and 18,175,898.75 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 | 72,703,595 | |
| -1 | 72,703,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 361 | 857 | 893 | 1,805 | 4,285 | 4,465 | 16,283 | 16,967 | 40,279 | 81,415 | 84,835 | 201,395 | 309,377 | 765,301 | 1,546,885 | 3,826,505 | 14,540,719 | 72,703,595 |
| -1 | -5 | -19 | -47 | -95 | -235 | -361 | -857 | -893 | -1,805 | -4,285 | -4,465 | -16,283 | -16,967 | -40,279 | -81,415 | -84,835 | -201,395 | -309,377 | -765,301 | -1,546,885 | -3,826,505 | -14,540,719 | -72,703,595 |
