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 19,073,225, 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 | 19,073,225 | |
| -1 | -19,073,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,073,225.
Example:
1 x 19,073,225 = 19,073,225
and
-1 x -19,073,225 = 19,073,225
Notice both answers equal 19,073,225
With that explanation out of the way, let's continue. Next, we take the number 19,073,225 and divide it by 2:
19,073,225 ÷ 2 = 9,536,612.5
If the quotient is a whole number, then 2 and 9,536,612.5 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 | 19,073,225 | |
| -1 | -19,073,225 |
Now, we try dividing 19,073,225 by 3:
19,073,225 ÷ 3 = 6,357,741.6667
If the quotient is a whole number, then 3 and 6,357,741.6667 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 | 19,073,225 | |
| -1 | -19,073,225 |
Let's try dividing by 4:
19,073,225 ÷ 4 = 4,768,306.25
If the quotient is a whole number, then 4 and 4,768,306.25 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 | 19,073,225 | |
| -1 | 19,073,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 67 | 193 | 295 | 335 | 965 | 1,475 | 1,675 | 3,953 | 4,825 | 11,387 | 12,931 | 19,765 | 56,935 | 64,655 | 98,825 | 284,675 | 323,275 | 762,929 | 3,814,645 | 19,073,225 |
| -1 | -5 | -25 | -59 | -67 | -193 | -295 | -335 | -965 | -1,475 | -1,675 | -3,953 | -4,825 | -11,387 | -12,931 | -19,765 | -56,935 | -64,655 | -98,825 | -284,675 | -323,275 | -762,929 | -3,814,645 | -19,073,225 |
