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 65,504,243, 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 | 65,504,243 | |
| -1 | -65,504,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,504,243.
Example:
1 x 65,504,243 = 65,504,243
and
-1 x -65,504,243 = 65,504,243
Notice both answers equal 65,504,243
With that explanation out of the way, let's continue. Next, we take the number 65,504,243 and divide it by 2:
65,504,243 ÷ 2 = 32,752,121.5
If the quotient is a whole number, then 2 and 32,752,121.5 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 | 65,504,243 | |
| -1 | -65,504,243 |
Now, we try dividing 65,504,243 by 3:
65,504,243 ÷ 3 = 21,834,747.6667
If the quotient is a whole number, then 3 and 21,834,747.6667 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 | 65,504,243 | |
| -1 | -65,504,243 |
Let's try dividing by 4:
65,504,243 ÷ 4 = 16,376,060.75
If the quotient is a whole number, then 4 and 16,376,060.75 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 | 65,504,243 | |
| -1 | 65,504,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 223 | 1,447 | 1,561 | 6,467 | 10,129 | 41,963 | 45,269 | 293,741 | 322,681 | 2,258,767 | 9,357,749 | 65,504,243 |
| -1 | -7 | -29 | -203 | -223 | -1,447 | -1,561 | -6,467 | -10,129 | -41,963 | -45,269 | -293,741 | -322,681 | -2,258,767 | -9,357,749 | -65,504,243 |
