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 76,300,085, 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 | 76,300,085 | |
| -1 | -76,300,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,300,085.
Example:
1 x 76,300,085 = 76,300,085
and
-1 x -76,300,085 = 76,300,085
Notice both answers equal 76,300,085
With that explanation out of the way, let's continue. Next, we take the number 76,300,085 and divide it by 2:
76,300,085 ÷ 2 = 38,150,042.5
If the quotient is a whole number, then 2 and 38,150,042.5 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 | 76,300,085 | |
| -1 | -76,300,085 |
Now, we try dividing 76,300,085 by 3:
76,300,085 ÷ 3 = 25,433,361.6667
If the quotient is a whole number, then 3 and 25,433,361.6667 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 | 76,300,085 | |
| -1 | -76,300,085 |
Let's try dividing by 4:
76,300,085 ÷ 4 = 19,075,021.25
If the quotient is a whole number, then 4 and 19,075,021.25 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 | 76,300,085 | |
| -1 | 76,300,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 463 | 1,433 | 2,315 | 7,165 | 10,649 | 32,959 | 53,245 | 164,795 | 663,479 | 3,317,395 | 15,260,017 | 76,300,085 |
| -1 | -5 | -23 | -115 | -463 | -1,433 | -2,315 | -7,165 | -10,649 | -32,959 | -53,245 | -164,795 | -663,479 | -3,317,395 | -15,260,017 | -76,300,085 |
