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 73,740,385, 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 | 73,740,385 | |
| -1 | -73,740,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,740,385.
Example:
1 x 73,740,385 = 73,740,385
and
-1 x -73,740,385 = 73,740,385
Notice both answers equal 73,740,385
With that explanation out of the way, let's continue. Next, we take the number 73,740,385 and divide it by 2:
73,740,385 ÷ 2 = 36,870,192.5
If the quotient is a whole number, then 2 and 36,870,192.5 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 | 73,740,385 | |
| -1 | -73,740,385 |
Now, we try dividing 73,740,385 by 3:
73,740,385 ÷ 3 = 24,580,128.3333
If the quotient is a whole number, then 3 and 24,580,128.3333 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 | 73,740,385 | |
| -1 | -73,740,385 |
Let's try dividing by 4:
73,740,385 ÷ 4 = 18,435,096.25
If the quotient is a whole number, then 4 and 18,435,096.25 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 | 73,740,385 | |
| -1 | 73,740,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 163 | 173 | 523 | 815 | 865 | 2,615 | 28,199 | 85,249 | 90,479 | 140,995 | 426,245 | 452,395 | 14,748,077 | 73,740,385 |
| -1 | -5 | -163 | -173 | -523 | -815 | -865 | -2,615 | -28,199 | -85,249 | -90,479 | -140,995 | -426,245 | -452,395 | -14,748,077 | -73,740,385 |
