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 19,459,225, 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 | 19,459,225 | |
| -1 | -19,459,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,459,225.
Example:
1 x 19,459,225 = 19,459,225
and
-1 x -19,459,225 = 19,459,225
Notice both answers equal 19,459,225
With that explanation out of the way, let's continue. Next, we take the number 19,459,225 and divide it by 2:
19,459,225 ÷ 2 = 9,729,612.5
If the quotient is a whole number, then 2 and 9,729,612.5 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 | 19,459,225 | |
| -1 | -19,459,225 |
Now, we try dividing 19,459,225 by 3:
19,459,225 ÷ 3 = 6,486,408.3333
If the quotient is a whole number, then 3 and 6,486,408.3333 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 | 19,459,225 | |
| -1 | -19,459,225 |
Let's try dividing by 4:
19,459,225 ÷ 4 = 4,864,806.25
If the quotient is a whole number, then 4 and 4,864,806.25 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 | 19,459,225 | |
| -1 | 19,459,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 109 | 185 | 193 | 545 | 925 | 965 | 2,725 | 4,033 | 4,825 | 7,141 | 20,165 | 21,037 | 35,705 | 100,825 | 105,185 | 178,525 | 525,925 | 778,369 | 3,891,845 | 19,459,225 |
| -1 | -5 | -25 | -37 | -109 | -185 | -193 | -545 | -925 | -965 | -2,725 | -4,033 | -4,825 | -7,141 | -20,165 | -21,037 | -35,705 | -100,825 | -105,185 | -178,525 | -525,925 | -778,369 | -3,891,845 | -19,459,225 |
