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 17,185,385, 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 | 17,185,385 | |
| -1 | -17,185,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,185,385.
Example:
1 x 17,185,385 = 17,185,385
and
-1 x -17,185,385 = 17,185,385
Notice both answers equal 17,185,385
With that explanation out of the way, let's continue. Next, we take the number 17,185,385 and divide it by 2:
17,185,385 ÷ 2 = 8,592,692.5
If the quotient is a whole number, then 2 and 8,592,692.5 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 | 17,185,385 | |
| -1 | -17,185,385 |
Now, we try dividing 17,185,385 by 3:
17,185,385 ÷ 3 = 5,728,461.6667
If the quotient is a whole number, then 3 and 5,728,461.6667 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 | 17,185,385 | |
| -1 | -17,185,385 |
Let's try dividing by 4:
17,185,385 ÷ 4 = 4,296,346.25
If the quotient is a whole number, then 4 and 4,296,346.25 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 | 17,185,385 | |
| -1 | 17,185,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 289 | 595 | 1,445 | 1,699 | 2,023 | 8,495 | 10,115 | 11,893 | 28,883 | 59,465 | 144,415 | 202,181 | 491,011 | 1,010,905 | 2,455,055 | 3,437,077 | 17,185,385 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -289 | -595 | -1,445 | -1,699 | -2,023 | -8,495 | -10,115 | -11,893 | -28,883 | -59,465 | -144,415 | -202,181 | -491,011 | -1,010,905 | -2,455,055 | -3,437,077 | -17,185,385 |
