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 65,464,165, 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 | 65,464,165 | |
| -1 | -65,464,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,464,165.
Example:
1 x 65,464,165 = 65,464,165
and
-1 x -65,464,165 = 65,464,165
Notice both answers equal 65,464,165
With that explanation out of the way, let's continue. Next, we take the number 65,464,165 and divide it by 2:
65,464,165 ÷ 2 = 32,732,082.5
If the quotient is a whole number, then 2 and 32,732,082.5 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 | 65,464,165 | |
| -1 | -65,464,165 |
Now, we try dividing 65,464,165 by 3:
65,464,165 ÷ 3 = 21,821,388.3333
If the quotient is a whole number, then 3 and 21,821,388.3333 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 | 65,464,165 | |
| -1 | -65,464,165 |
Let's try dividing by 4:
65,464,165 ÷ 4 = 16,366,041.25
If the quotient is a whole number, then 4 and 16,366,041.25 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 | 65,464,165 | |
| -1 | 65,464,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 377 | 1,885 | 34,729 | 173,645 | 451,477 | 1,007,141 | 2,257,385 | 5,035,705 | 13,092,833 | 65,464,165 |
| -1 | -5 | -13 | -29 | -65 | -145 | -377 | -1,885 | -34,729 | -173,645 | -451,477 | -1,007,141 | -2,257,385 | -5,035,705 | -13,092,833 | -65,464,165 |
