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 104,365,145, 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 | 104,365,145 | |
| -1 | -104,365,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,365,145.
Example:
1 x 104,365,145 = 104,365,145
and
-1 x -104,365,145 = 104,365,145
Notice both answers equal 104,365,145
With that explanation out of the way, let's continue. Next, we take the number 104,365,145 and divide it by 2:
104,365,145 ÷ 2 = 52,182,572.5
If the quotient is a whole number, then 2 and 52,182,572.5 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 | 104,365,145 | |
| -1 | -104,365,145 |
Now, we try dividing 104,365,145 by 3:
104,365,145 ÷ 3 = 34,788,381.6667
If the quotient is a whole number, then 3 and 34,788,381.6667 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 | 104,365,145 | |
| -1 | -104,365,145 |
Let's try dividing by 4:
104,365,145 ÷ 4 = 26,091,286.25
If the quotient is a whole number, then 4 and 26,091,286.25 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 | 104,365,145 | |
| -1 | 104,365,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 47 | 115 | 235 | 1,081 | 5,405 | 19,309 | 96,545 | 444,107 | 907,523 | 2,220,535 | 4,537,615 | 20,873,029 | 104,365,145 |
| -1 | -5 | -23 | -47 | -115 | -235 | -1,081 | -5,405 | -19,309 | -96,545 | -444,107 | -907,523 | -2,220,535 | -4,537,615 | -20,873,029 | -104,365,145 |
