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 17,738,455, 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 | 17,738,455 | |
| -1 | -17,738,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,738,455.
Example:
1 x 17,738,455 = 17,738,455
and
-1 x -17,738,455 = 17,738,455
Notice both answers equal 17,738,455
With that explanation out of the way, let's continue. Next, we take the number 17,738,455 and divide it by 2:
17,738,455 ÷ 2 = 8,869,227.5
If the quotient is a whole number, then 2 and 8,869,227.5 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 | 17,738,455 | |
| -1 | -17,738,455 |
Now, we try dividing 17,738,455 by 3:
17,738,455 ÷ 3 = 5,912,818.3333
If the quotient is a whole number, then 3 and 5,912,818.3333 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 | 17,738,455 | |
| -1 | -17,738,455 |
Let's try dividing by 4:
17,738,455 ÷ 4 = 4,434,613.75
If the quotient is a whole number, then 4 and 4,434,613.75 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 | 17,738,455 | |
| -1 | 17,738,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 1,109 | 2,285 | 3,199 | 5,545 | 7,763 | 15,995 | 38,815 | 506,813 | 2,534,065 | 3,547,691 | 17,738,455 |
| -1 | -5 | -7 | -35 | -457 | -1,109 | -2,285 | -3,199 | -5,545 | -7,763 | -15,995 | -38,815 | -506,813 | -2,534,065 | -3,547,691 | -17,738,455 |
