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 73,475,647, 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 | 73,475,647 | |
| -1 | -73,475,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,475,647.
Example:
1 x 73,475,647 = 73,475,647
and
-1 x -73,475,647 = 73,475,647
Notice both answers equal 73,475,647
With that explanation out of the way, let's continue. Next, we take the number 73,475,647 and divide it by 2:
73,475,647 ÷ 2 = 36,737,823.5
If the quotient is a whole number, then 2 and 36,737,823.5 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 | 73,475,647 | |
| -1 | -73,475,647 |
Now, we try dividing 73,475,647 by 3:
73,475,647 ÷ 3 = 24,491,882.3333
If the quotient is a whole number, then 3 and 24,491,882.3333 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 | 73,475,647 | |
| -1 | -73,475,647 |
Let's try dividing by 4:
73,475,647 ÷ 4 = 18,368,911.75
If the quotient is a whole number, then 4 and 18,368,911.75 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 | 73,475,647 | |
| -1 | 73,475,647 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 203 | 841 | 1,421 | 1,783 | 5,887 | 12,481 | 41,209 | 51,707 | 87,367 | 361,949 | 1,499,503 | 2,533,643 | 10,496,521 | 73,475,647 |
| -1 | -7 | -29 | -49 | -203 | -841 | -1,421 | -1,783 | -5,887 | -12,481 | -41,209 | -51,707 | -87,367 | -361,949 | -1,499,503 | -2,533,643 | -10,496,521 | -73,475,647 |
