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 60,060,605, 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 | 60,060,605 | |
| -1 | -60,060,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,060,605.
Example:
1 x 60,060,605 = 60,060,605
and
-1 x -60,060,605 = 60,060,605
Notice both answers equal 60,060,605
With that explanation out of the way, let's continue. Next, we take the number 60,060,605 and divide it by 2:
60,060,605 ÷ 2 = 30,030,302.5
If the quotient is a whole number, then 2 and 30,030,302.5 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 | 60,060,605 | |
| -1 | -60,060,605 |
Now, we try dividing 60,060,605 by 3:
60,060,605 ÷ 3 = 20,020,201.6667
If the quotient is a whole number, then 3 and 20,020,201.6667 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 | 60,060,605 | |
| -1 | -60,060,605 |
Let's try dividing by 4:
60,060,605 ÷ 4 = 15,015,151.25
If the quotient is a whole number, then 4 and 15,015,151.25 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 | 60,060,605 | |
| -1 | 60,060,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 293 | 1,465 | 3,223 | 3,727 | 16,115 | 18,635 | 40,997 | 204,985 | 1,092,011 | 5,460,055 | 12,012,121 | 60,060,605 |
| -1 | -5 | -11 | -55 | -293 | -1,465 | -3,223 | -3,727 | -16,115 | -18,635 | -40,997 | -204,985 | -1,092,011 | -5,460,055 | -12,012,121 | -60,060,605 |
