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 60,535,405, 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 | 60,535,405 | |
| -1 | -60,535,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,535,405.
Example:
1 x 60,535,405 = 60,535,405
and
-1 x -60,535,405 = 60,535,405
Notice both answers equal 60,535,405
With that explanation out of the way, let's continue. Next, we take the number 60,535,405 and divide it by 2:
60,535,405 ÷ 2 = 30,267,702.5
If the quotient is a whole number, then 2 and 30,267,702.5 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 | 60,535,405 | |
| -1 | -60,535,405 |
Now, we try dividing 60,535,405 by 3:
60,535,405 ÷ 3 = 20,178,468.3333
If the quotient is a whole number, then 3 and 20,178,468.3333 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 | 60,535,405 | |
| -1 | -60,535,405 |
Let's try dividing by 4:
60,535,405 ÷ 4 = 15,133,851.25
If the quotient is a whole number, then 4 and 15,133,851.25 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 | 60,535,405 | |
| -1 | 60,535,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 55,793 | 278,965 | 390,551 | 1,729,583 | 1,952,755 | 8,647,915 | 12,107,081 | 60,535,405 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -55,793 | -278,965 | -390,551 | -1,729,583 | -1,952,755 | -8,647,915 | -12,107,081 | -60,535,405 |
