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, 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 | |
| -1 | -60,775 |
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.
Example:
1 x 60,775 = 60,775
and
-1 x -60,775 = 60,775
Notice both answers equal 60,775
With that explanation out of the way, let's continue. Next, we take the number 60,775 and divide it by 2:
60,775 ÷ 2 = 30,387.5
If the quotient is a whole number, then 2 and 30,387.5 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 | |
| -1 | -60,775 |
Now, we try dividing 60,775 by 3:
60,775 ÷ 3 = 20,258.3333
If the quotient is a whole number, then 3 and 20,258.3333 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 | 60,775 | |
| -1 | -60,775 |
Let's try dividing by 4:
60,775 ÷ 4 = 15,193.75
If the quotient is a whole number, then 4 and 15,193.75 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 | 60,775 | |
| -1 | 60,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 17 | 25 | 55 | 65 | 85 | 143 | 187 | 221 | 275 | 325 | 425 | 715 | 935 | 1,105 | 2,431 | 3,575 | 4,675 | 5,525 | 12,155 | 60,775 |
| -1 | -5 | -11 | -13 | -17 | -25 | -55 | -65 | -85 | -143 | -187 | -221 | -275 | -325 | -425 | -715 | -935 | -1,105 | -2,431 | -3,575 | -4,675 | -5,525 | -12,155 | -60,775 |
