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 68,483,365, 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 | 68,483,365 | |
| -1 | -68,483,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,483,365.
Example:
1 x 68,483,365 = 68,483,365
and
-1 x -68,483,365 = 68,483,365
Notice both answers equal 68,483,365
With that explanation out of the way, let's continue. Next, we take the number 68,483,365 and divide it by 2:
68,483,365 ÷ 2 = 34,241,682.5
If the quotient is a whole number, then 2 and 34,241,682.5 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 | 68,483,365 | |
| -1 | -68,483,365 |
Now, we try dividing 68,483,365 by 3:
68,483,365 ÷ 3 = 22,827,788.3333
If the quotient is a whole number, then 3 and 22,827,788.3333 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 | 68,483,365 | |
| -1 | -68,483,365 |
Let's try dividing by 4:
68,483,365 ÷ 4 = 17,120,841.25
If the quotient is a whole number, then 4 and 17,120,841.25 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 | 68,483,365 | |
| -1 | 68,483,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 269 | 295 | 863 | 1,345 | 4,315 | 15,871 | 50,917 | 79,355 | 232,147 | 254,585 | 1,160,735 | 13,696,673 | 68,483,365 |
| -1 | -5 | -59 | -269 | -295 | -863 | -1,345 | -4,315 | -15,871 | -50,917 | -79,355 | -232,147 | -254,585 | -1,160,735 | -13,696,673 | -68,483,365 |
