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 60,506,165, 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 | 60,506,165 | |
| -1 | -60,506,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,506,165.
Example:
1 x 60,506,165 = 60,506,165
and
-1 x -60,506,165 = 60,506,165
Notice both answers equal 60,506,165
With that explanation out of the way, let's continue. Next, we take the number 60,506,165 and divide it by 2:
60,506,165 ÷ 2 = 30,253,082.5
If the quotient is a whole number, then 2 and 30,253,082.5 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 | 60,506,165 | |
| -1 | -60,506,165 |
Now, we try dividing 60,506,165 by 3:
60,506,165 ÷ 3 = 20,168,721.6667
If the quotient is a whole number, then 3 and 20,168,721.6667 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 | 60,506,165 | |
| -1 | -60,506,165 |
Let's try dividing by 4:
60,506,165 ÷ 4 = 15,126,541.25
If the quotient is a whole number, then 4 and 15,126,541.25 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 | 60,506,165 | |
| -1 | 60,506,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 613 | 1,039 | 3,065 | 5,195 | 11,647 | 19,741 | 58,235 | 98,705 | 636,907 | 3,184,535 | 12,101,233 | 60,506,165 |
| -1 | -5 | -19 | -95 | -613 | -1,039 | -3,065 | -5,195 | -11,647 | -19,741 | -58,235 | -98,705 | -636,907 | -3,184,535 | -12,101,233 | -60,506,165 |
