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 104,405,525, 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 | 104,405,525 | |
| -1 | -104,405,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,405,525.
Example:
1 x 104,405,525 = 104,405,525
and
-1 x -104,405,525 = 104,405,525
Notice both answers equal 104,405,525
With that explanation out of the way, let's continue. Next, we take the number 104,405,525 and divide it by 2:
104,405,525 ÷ 2 = 52,202,762.5
If the quotient is a whole number, then 2 and 52,202,762.5 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 | 104,405,525 | |
| -1 | -104,405,525 |
Now, we try dividing 104,405,525 by 3:
104,405,525 ÷ 3 = 34,801,841.6667
If the quotient is a whole number, then 3 and 34,801,841.6667 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 | 104,405,525 | |
| -1 | -104,405,525 |
Let's try dividing by 4:
104,405,525 ÷ 4 = 26,101,381.25
If the quotient is a whole number, then 4 and 26,101,381.25 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 | 104,405,525 | |
| -1 | 104,405,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 85,229 | 426,145 | 596,603 | 2,130,725 | 2,983,015 | 4,176,221 | 14,915,075 | 20,881,105 | 104,405,525 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -85,229 | -426,145 | -596,603 | -2,130,725 | -2,983,015 | -4,176,221 | -14,915,075 | -20,881,105 | -104,405,525 |
