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 17,027,525, 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 | 17,027,525 | |
| -1 | -17,027,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,027,525.
Example:
1 x 17,027,525 = 17,027,525
and
-1 x -17,027,525 = 17,027,525
Notice both answers equal 17,027,525
With that explanation out of the way, let's continue. Next, we take the number 17,027,525 and divide it by 2:
17,027,525 ÷ 2 = 8,513,762.5
If the quotient is a whole number, then 2 and 8,513,762.5 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 | 17,027,525 | |
| -1 | -17,027,525 |
Now, we try dividing 17,027,525 by 3:
17,027,525 ÷ 3 = 5,675,841.6667
If the quotient is a whole number, then 3 and 5,675,841.6667 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 | 17,027,525 | |
| -1 | -17,027,525 |
Let's try dividing by 4:
17,027,525 ÷ 4 = 4,256,881.25
If the quotient is a whole number, then 4 and 4,256,881.25 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 | 17,027,525 | |
| -1 | 17,027,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 127 | 155 | 173 | 635 | 775 | 865 | 3,175 | 3,937 | 4,325 | 5,363 | 19,685 | 21,971 | 26,815 | 98,425 | 109,855 | 134,075 | 549,275 | 681,101 | 3,405,505 | 17,027,525 |
| -1 | -5 | -25 | -31 | -127 | -155 | -173 | -635 | -775 | -865 | -3,175 | -3,937 | -4,325 | -5,363 | -19,685 | -21,971 | -26,815 | -98,425 | -109,855 | -134,075 | -549,275 | -681,101 | -3,405,505 | -17,027,525 |
