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 60,216,085, 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 | 60,216,085 | |
| -1 | -60,216,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,216,085.
Example:
1 x 60,216,085 = 60,216,085
and
-1 x -60,216,085 = 60,216,085
Notice both answers equal 60,216,085
With that explanation out of the way, let's continue. Next, we take the number 60,216,085 and divide it by 2:
60,216,085 ÷ 2 = 30,108,042.5
If the quotient is a whole number, then 2 and 30,108,042.5 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 | 60,216,085 | |
| -1 | -60,216,085 |
Now, we try dividing 60,216,085 by 3:
60,216,085 ÷ 3 = 20,072,028.3333
If the quotient is a whole number, then 3 and 20,072,028.3333 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 | 60,216,085 | |
| -1 | -60,216,085 |
Let's try dividing by 4:
60,216,085 ÷ 4 = 15,054,021.25
If the quotient is a whole number, then 4 and 15,054,021.25 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 | 60,216,085 | |
| -1 | 60,216,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 83 | 205 | 415 | 3,403 | 3,539 | 17,015 | 17,695 | 145,099 | 293,737 | 725,495 | 1,468,685 | 12,043,217 | 60,216,085 |
| -1 | -5 | -41 | -83 | -205 | -415 | -3,403 | -3,539 | -17,015 | -17,695 | -145,099 | -293,737 | -725,495 | -1,468,685 | -12,043,217 | -60,216,085 |
