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 65,244,641, 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 | 65,244,641 | |
| -1 | -65,244,641 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,244,641.
Example:
1 x 65,244,641 = 65,244,641
and
-1 x -65,244,641 = 65,244,641
Notice both answers equal 65,244,641
With that explanation out of the way, let's continue. Next, we take the number 65,244,641 and divide it by 2:
65,244,641 ÷ 2 = 32,622,320.5
If the quotient is a whole number, then 2 and 32,622,320.5 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 | 65,244,641 | |
| -1 | -65,244,641 |
Now, we try dividing 65,244,641 by 3:
65,244,641 ÷ 3 = 21,748,213.6667
If the quotient is a whole number, then 3 and 21,748,213.6667 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 | 65,244,641 | |
| -1 | -65,244,641 |
Let's try dividing by 4:
65,244,641 ÷ 4 = 16,311,160.25
If the quotient is a whole number, then 4 and 16,311,160.25 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 | 65,244,641 | |
| -1 | 65,244,641 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 107 | 749 | 1,177 | 7,919 | 8,239 | 55,433 | 87,109 | 609,763 | 847,333 | 5,931,331 | 9,320,663 | 65,244,641 |
| -1 | -7 | -11 | -77 | -107 | -749 | -1,177 | -7,919 | -8,239 | -55,433 | -87,109 | -609,763 | -847,333 | -5,931,331 | -9,320,663 | -65,244,641 |
