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 103,000,325, 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 | 103,000,325 | |
| -1 | -103,000,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,000,325.
Example:
1 x 103,000,325 = 103,000,325
and
-1 x -103,000,325 = 103,000,325
Notice both answers equal 103,000,325
With that explanation out of the way, let's continue. Next, we take the number 103,000,325 and divide it by 2:
103,000,325 ÷ 2 = 51,500,162.5
If the quotient is a whole number, then 2 and 51,500,162.5 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 | 103,000,325 | |
| -1 | -103,000,325 |
Now, we try dividing 103,000,325 by 3:
103,000,325 ÷ 3 = 34,333,441.6667
If the quotient is a whole number, then 3 and 34,333,441.6667 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 | 103,000,325 | |
| -1 | -103,000,325 |
Let's try dividing by 4:
103,000,325 ÷ 4 = 25,750,081.25
If the quotient is a whole number, then 4 and 25,750,081.25 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 | 103,000,325 | |
| -1 | 103,000,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 271 | 575 | 661 | 1,355 | 3,305 | 6,233 | 6,775 | 15,203 | 16,525 | 31,165 | 76,015 | 155,825 | 179,131 | 380,075 | 895,655 | 4,120,013 | 4,478,275 | 20,600,065 | 103,000,325 |
| -1 | -5 | -23 | -25 | -115 | -271 | -575 | -661 | -1,355 | -3,305 | -6,233 | -6,775 | -15,203 | -16,525 | -31,165 | -76,015 | -155,825 | -179,131 | -380,075 | -895,655 | -4,120,013 | -4,478,275 | -20,600,065 | -103,000,325 |
