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 17,011,225, 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 | 17,011,225 | |
| -1 | -17,011,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,011,225.
Example:
1 x 17,011,225 = 17,011,225
and
-1 x -17,011,225 = 17,011,225
Notice both answers equal 17,011,225
With that explanation out of the way, let's continue. Next, we take the number 17,011,225 and divide it by 2:
17,011,225 ÷ 2 = 8,505,612.5
If the quotient is a whole number, then 2 and 8,505,612.5 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 | 17,011,225 | |
| -1 | -17,011,225 |
Now, we try dividing 17,011,225 by 3:
17,011,225 ÷ 3 = 5,670,408.3333
If the quotient is a whole number, then 3 and 5,670,408.3333 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 | 17,011,225 | |
| -1 | -17,011,225 |
Let's try dividing by 4:
17,011,225 ÷ 4 = 4,252,806.25
If the quotient is a whole number, then 4 and 4,252,806.25 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 | 17,011,225 | |
| -1 | 17,011,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 8,837 | 44,185 | 61,859 | 97,207 | 220,925 | 309,295 | 486,035 | 680,449 | 1,546,475 | 2,430,175 | 3,402,245 | 17,011,225 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -8,837 | -44,185 | -61,859 | -97,207 | -220,925 | -309,295 | -486,035 | -680,449 | -1,546,475 | -2,430,175 | -3,402,245 | -17,011,225 |
