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 60,775,913, 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 | 60,775,913 | |
| -1 | -60,775,913 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,775,913.
Example:
1 x 60,775,913 = 60,775,913
and
-1 x -60,775,913 = 60,775,913
Notice both answers equal 60,775,913
With that explanation out of the way, let's continue. Next, we take the number 60,775,913 and divide it by 2:
60,775,913 ÷ 2 = 30,387,956.5
If the quotient is a whole number, then 2 and 30,387,956.5 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 | 60,775,913 | |
| -1 | -60,775,913 |
Now, we try dividing 60,775,913 by 3:
60,775,913 ÷ 3 = 20,258,637.6667
If the quotient is a whole number, then 3 and 20,258,637.6667 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 | 60,775,913 | |
| -1 | -60,775,913 |
Let's try dividing by 4:
60,775,913 ÷ 4 = 15,193,978.25
If the quotient is a whole number, then 4 and 15,193,978.25 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 | 60,775,913 | |
| -1 | 60,775,913 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 229 | 253 | 1,049 | 2,519 | 5,267 | 11,539 | 24,127 | 57,937 | 240,221 | 265,397 | 2,642,431 | 5,525,083 | 60,775,913 |
| -1 | -11 | -23 | -229 | -253 | -1,049 | -2,519 | -5,267 | -11,539 | -24,127 | -57,937 | -240,221 | -265,397 | -2,642,431 | -5,525,083 | -60,775,913 |
