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 65,235,653, 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 | 65,235,653 | |
| -1 | -65,235,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,235,653.
Example:
1 x 65,235,653 = 65,235,653
and
-1 x -65,235,653 = 65,235,653
Notice both answers equal 65,235,653
With that explanation out of the way, let's continue. Next, we take the number 65,235,653 and divide it by 2:
65,235,653 ÷ 2 = 32,617,826.5
If the quotient is a whole number, then 2 and 32,617,826.5 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 | 65,235,653 | |
| -1 | -65,235,653 |
Now, we try dividing 65,235,653 by 3:
65,235,653 ÷ 3 = 21,745,217.6667
If the quotient is a whole number, then 3 and 21,745,217.6667 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 | 65,235,653 | |
| -1 | -65,235,653 |
Let's try dividing by 4:
65,235,653 ÷ 4 = 16,308,913.25
If the quotient is a whole number, then 4 and 16,308,913.25 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 | 65,235,653 | |
| -1 | 65,235,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 107 | 251 | 347 | 749 | 1,757 | 2,429 | 26,857 | 37,129 | 87,097 | 187,999 | 259,903 | 609,679 | 9,319,379 | 65,235,653 |
| -1 | -7 | -107 | -251 | -347 | -749 | -1,757 | -2,429 | -26,857 | -37,129 | -87,097 | -187,999 | -259,903 | -609,679 | -9,319,379 | -65,235,653 |
