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 19,447,025, 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 | 19,447,025 | |
| -1 | -19,447,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,447,025.
Example:
1 x 19,447,025 = 19,447,025
and
-1 x -19,447,025 = 19,447,025
Notice both answers equal 19,447,025
With that explanation out of the way, let's continue. Next, we take the number 19,447,025 and divide it by 2:
19,447,025 ÷ 2 = 9,723,512.5
If the quotient is a whole number, then 2 and 9,723,512.5 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 | 19,447,025 | |
| -1 | -19,447,025 |
Now, we try dividing 19,447,025 by 3:
19,447,025 ÷ 3 = 6,482,341.6667
If the quotient is a whole number, then 3 and 6,482,341.6667 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 | 19,447,025 | |
| -1 | -19,447,025 |
Let's try dividing by 4:
19,447,025 ÷ 4 = 4,861,756.25
If the quotient is a whole number, then 4 and 4,861,756.25 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 | 19,447,025 | |
| -1 | 19,447,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 53 | 65 | 265 | 325 | 689 | 1,129 | 1,325 | 3,445 | 5,645 | 14,677 | 17,225 | 28,225 | 59,837 | 73,385 | 299,185 | 366,925 | 777,881 | 1,495,925 | 3,889,405 | 19,447,025 |
| -1 | -5 | -13 | -25 | -53 | -65 | -265 | -325 | -689 | -1,129 | -1,325 | -3,445 | -5,645 | -14,677 | -17,225 | -28,225 | -59,837 | -73,385 | -299,185 | -366,925 | -777,881 | -1,495,925 | -3,889,405 | -19,447,025 |
