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 19,550,495, 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 | 19,550,495 | |
| -1 | -19,550,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,550,495.
Example:
1 x 19,550,495 = 19,550,495
and
-1 x -19,550,495 = 19,550,495
Notice both answers equal 19,550,495
With that explanation out of the way, let's continue. Next, we take the number 19,550,495 and divide it by 2:
19,550,495 ÷ 2 = 9,775,247.5
If the quotient is a whole number, then 2 and 9,775,247.5 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 | 19,550,495 | |
| -1 | -19,550,495 |
Now, we try dividing 19,550,495 by 3:
19,550,495 ÷ 3 = 6,516,831.6667
If the quotient is a whole number, then 3 and 6,516,831.6667 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 | 19,550,495 | |
| -1 | -19,550,495 |
Let's try dividing by 4:
19,550,495 ÷ 4 = 4,887,623.75
If the quotient is a whole number, then 4 and 4,887,623.75 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 | 19,550,495 | |
| -1 | 19,550,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 73 | 145 | 365 | 1,847 | 2,117 | 9,235 | 10,585 | 53,563 | 134,831 | 267,815 | 674,155 | 3,910,099 | 19,550,495 |
| -1 | -5 | -29 | -73 | -145 | -365 | -1,847 | -2,117 | -9,235 | -10,585 | -53,563 | -134,831 | -267,815 | -674,155 | -3,910,099 | -19,550,495 |
