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 73,515,725, 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 | 73,515,725 | |
| -1 | -73,515,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,515,725.
Example:
1 x 73,515,725 = 73,515,725
and
-1 x -73,515,725 = 73,515,725
Notice both answers equal 73,515,725
With that explanation out of the way, let's continue. Next, we take the number 73,515,725 and divide it by 2:
73,515,725 ÷ 2 = 36,757,862.5
If the quotient is a whole number, then 2 and 36,757,862.5 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 | 73,515,725 | |
| -1 | -73,515,725 |
Now, we try dividing 73,515,725 by 3:
73,515,725 ÷ 3 = 24,505,241.6667
If the quotient is a whole number, then 3 and 24,505,241.6667 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 | 73,515,725 | |
| -1 | -73,515,725 |
Let's try dividing by 4:
73,515,725 ÷ 4 = 18,378,931.25
If the quotient is a whole number, then 4 and 18,378,931.25 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 | 73,515,725 | |
| -1 | 73,515,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 31 | 145 | 155 | 725 | 775 | 899 | 3,271 | 4,495 | 16,355 | 22,475 | 81,775 | 94,859 | 101,401 | 474,295 | 507,005 | 2,371,475 | 2,535,025 | 2,940,629 | 14,703,145 | 73,515,725 |
| -1 | -5 | -25 | -29 | -31 | -145 | -155 | -725 | -775 | -899 | -3,271 | -4,495 | -16,355 | -22,475 | -81,775 | -94,859 | -101,401 | -474,295 | -507,005 | -2,371,475 | -2,535,025 | -2,940,629 | -14,703,145 | -73,515,725 |
