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 65,013,307, 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 | 65,013,307 | |
| -1 | -65,013,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,013,307.
Example:
1 x 65,013,307 = 65,013,307
and
-1 x -65,013,307 = 65,013,307
Notice both answers equal 65,013,307
With that explanation out of the way, let's continue. Next, we take the number 65,013,307 and divide it by 2:
65,013,307 ÷ 2 = 32,506,653.5
If the quotient is a whole number, then 2 and 32,506,653.5 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 | 65,013,307 | |
| -1 | -65,013,307 |
Now, we try dividing 65,013,307 by 3:
65,013,307 ÷ 3 = 21,671,102.3333
If the quotient is a whole number, then 3 and 21,671,102.3333 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 | 65,013,307 | |
| -1 | -65,013,307 |
Let's try dividing by 4:
65,013,307 ÷ 4 = 16,253,326.75
If the quotient is a whole number, then 4 and 16,253,326.75 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 | 65,013,307 | |
| -1 | 65,013,307 |
If you did it right, you will end up with this table:
| 1 | 19 | 107 | 113 | 283 | 2,033 | 2,147 | 5,377 | 12,091 | 30,281 | 31,979 | 229,729 | 575,339 | 607,601 | 3,421,753 | 65,013,307 |
| -1 | -19 | -107 | -113 | -283 | -2,033 | -2,147 | -5,377 | -12,091 | -30,281 | -31,979 | -229,729 | -575,339 | -607,601 | -3,421,753 | -65,013,307 |
