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 65,647,153, 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 | 65,647,153 | |
| -1 | -65,647,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,647,153.
Example:
1 x 65,647,153 = 65,647,153
and
-1 x -65,647,153 = 65,647,153
Notice both answers equal 65,647,153
With that explanation out of the way, let's continue. Next, we take the number 65,647,153 and divide it by 2:
65,647,153 ÷ 2 = 32,823,576.5
If the quotient is a whole number, then 2 and 32,823,576.5 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 | 65,647,153 | |
| -1 | -65,647,153 |
Now, we try dividing 65,647,153 by 3:
65,647,153 ÷ 3 = 21,882,384.3333
If the quotient is a whole number, then 3 and 21,882,384.3333 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 | 65,647,153 | |
| -1 | -65,647,153 |
Let's try dividing by 4:
65,647,153 ÷ 4 = 16,411,788.25
If the quotient is a whole number, then 4 and 16,411,788.25 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 | 65,647,153 | |
| -1 | 65,647,153 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 103 | 143 | 1,133 | 1,339 | 4,457 | 14,729 | 49,027 | 57,941 | 459,071 | 637,351 | 5,049,781 | 5,967,923 | 65,647,153 |
| -1 | -11 | -13 | -103 | -143 | -1,133 | -1,339 | -4,457 | -14,729 | -49,027 | -57,941 | -459,071 | -637,351 | -5,049,781 | -5,967,923 | -65,647,153 |
