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 101,040,325, 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 | 101,040,325 | |
| -1 | -101,040,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,040,325.
Example:
1 x 101,040,325 = 101,040,325
and
-1 x -101,040,325 = 101,040,325
Notice both answers equal 101,040,325
With that explanation out of the way, let's continue. Next, we take the number 101,040,325 and divide it by 2:
101,040,325 ÷ 2 = 50,520,162.5
If the quotient is a whole number, then 2 and 50,520,162.5 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 | 101,040,325 | |
| -1 | -101,040,325 |
Now, we try dividing 101,040,325 by 3:
101,040,325 ÷ 3 = 33,680,108.3333
If the quotient is a whole number, then 3 and 33,680,108.3333 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 | 101,040,325 | |
| -1 | -101,040,325 |
Let's try dividing by 4:
101,040,325 ÷ 4 = 25,260,081.25
If the quotient is a whole number, then 4 and 25,260,081.25 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 | 101,040,325 | |
| -1 | 101,040,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 193 | 215 | 487 | 965 | 1,075 | 2,435 | 4,825 | 8,299 | 12,175 | 20,941 | 41,495 | 93,991 | 104,705 | 207,475 | 469,955 | 523,525 | 2,349,775 | 4,041,613 | 20,208,065 | 101,040,325 |
| -1 | -5 | -25 | -43 | -193 | -215 | -487 | -965 | -1,075 | -2,435 | -4,825 | -8,299 | -12,175 | -20,941 | -41,495 | -93,991 | -104,705 | -207,475 | -469,955 | -523,525 | -2,349,775 | -4,041,613 | -20,208,065 | -101,040,325 |
