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 60,902,335, 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 | 60,902,335 | |
| -1 | -60,902,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,902,335.
Example:
1 x 60,902,335 = 60,902,335
and
-1 x -60,902,335 = 60,902,335
Notice both answers equal 60,902,335
With that explanation out of the way, let's continue. Next, we take the number 60,902,335 and divide it by 2:
60,902,335 ÷ 2 = 30,451,167.5
If the quotient is a whole number, then 2 and 30,451,167.5 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 | 60,902,335 | |
| -1 | -60,902,335 |
Now, we try dividing 60,902,335 by 3:
60,902,335 ÷ 3 = 20,300,778.3333
If the quotient is a whole number, then 3 and 20,300,778.3333 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 | 60,902,335 | |
| -1 | -60,902,335 |
Let's try dividing by 4:
60,902,335 ÷ 4 = 15,225,583.75
If the quotient is a whole number, then 4 and 15,225,583.75 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 | 60,902,335 | |
| -1 | 60,902,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 601 | 1,559 | 3,005 | 7,795 | 7,813 | 20,267 | 39,065 | 101,335 | 936,959 | 4,684,795 | 12,180,467 | 60,902,335 |
| -1 | -5 | -13 | -65 | -601 | -1,559 | -3,005 | -7,795 | -7,813 | -20,267 | -39,065 | -101,335 | -936,959 | -4,684,795 | -12,180,467 | -60,902,335 |
