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 73,667,405, 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 | 73,667,405 | |
| -1 | -73,667,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,667,405.
Example:
1 x 73,667,405 = 73,667,405
and
-1 x -73,667,405 = 73,667,405
Notice both answers equal 73,667,405
With that explanation out of the way, let's continue. Next, we take the number 73,667,405 and divide it by 2:
73,667,405 ÷ 2 = 36,833,702.5
If the quotient is a whole number, then 2 and 36,833,702.5 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 | 73,667,405 | |
| -1 | -73,667,405 |
Now, we try dividing 73,667,405 by 3:
73,667,405 ÷ 3 = 24,555,801.6667
If the quotient is a whole number, then 3 and 24,555,801.6667 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 | 73,667,405 | |
| -1 | -73,667,405 |
Let's try dividing by 4:
73,667,405 ÷ 4 = 18,416,851.25
If the quotient is a whole number, then 4 and 18,416,851.25 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 | 73,667,405 | |
| -1 | 73,667,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,223 | 1,721 | 6,115 | 8,561 | 8,605 | 12,047 | 42,805 | 60,235 | 2,104,783 | 10,523,915 | 14,733,481 | 73,667,405 |
| -1 | -5 | -7 | -35 | -1,223 | -1,721 | -6,115 | -8,561 | -8,605 | -12,047 | -42,805 | -60,235 | -2,104,783 | -10,523,915 | -14,733,481 | -73,667,405 |
