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 65,925,521, 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 | 65,925,521 | |
| -1 | -65,925,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,925,521.
Example:
1 x 65,925,521 = 65,925,521
and
-1 x -65,925,521 = 65,925,521
Notice both answers equal 65,925,521
With that explanation out of the way, let's continue. Next, we take the number 65,925,521 and divide it by 2:
65,925,521 ÷ 2 = 32,962,760.5
If the quotient is a whole number, then 2 and 32,962,760.5 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 | 65,925,521 | |
| -1 | -65,925,521 |
Now, we try dividing 65,925,521 by 3:
65,925,521 ÷ 3 = 21,975,173.6667
If the quotient is a whole number, then 3 and 21,975,173.6667 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 | 65,925,521 | |
| -1 | -65,925,521 |
Let's try dividing by 4:
65,925,521 ÷ 4 = 16,481,380.25
If the quotient is a whole number, then 4 and 16,481,380.25 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 | 65,925,521 | |
| -1 | 65,925,521 |
If you did it right, you will end up with this table:
| 1 | 23 | 67 | 179 | 239 | 1,541 | 4,117 | 5,497 | 11,993 | 16,013 | 42,781 | 275,839 | 368,299 | 983,963 | 2,866,327 | 65,925,521 |
| -1 | -23 | -67 | -179 | -239 | -1,541 | -4,117 | -5,497 | -11,993 | -16,013 | -42,781 | -275,839 | -368,299 | -983,963 | -2,866,327 | -65,925,521 |
