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 76,205,375, 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 | 76,205,375 | |
| -1 | -76,205,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,205,375.
Example:
1 x 76,205,375 = 76,205,375
and
-1 x -76,205,375 = 76,205,375
Notice both answers equal 76,205,375
With that explanation out of the way, let's continue. Next, we take the number 76,205,375 and divide it by 2:
76,205,375 ÷ 2 = 38,102,687.5
If the quotient is a whole number, then 2 and 38,102,687.5 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 | 76,205,375 | |
| -1 | -76,205,375 |
Now, we try dividing 76,205,375 by 3:
76,205,375 ÷ 3 = 25,401,791.6667
If the quotient is a whole number, then 3 and 25,401,791.6667 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 | 76,205,375 | |
| -1 | -76,205,375 |
Let's try dividing by 4:
76,205,375 ÷ 4 = 19,051,343.75
If the quotient is a whole number, then 4 and 19,051,343.75 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 | 76,205,375 | |
| -1 | 76,205,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 125 | 395 | 1,975 | 7,717 | 9,875 | 38,585 | 192,925 | 609,643 | 964,625 | 3,048,215 | 15,241,075 | 76,205,375 |
| -1 | -5 | -25 | -79 | -125 | -395 | -1,975 | -7,717 | -9,875 | -38,585 | -192,925 | -609,643 | -964,625 | -3,048,215 | -15,241,075 | -76,205,375 |
