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 17,587,711, 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 | 17,587,711 | |
-1 | -17,587,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,587,711.
Example:
1 x 17,587,711 = 17,587,711
and
-1 x -17,587,711 = 17,587,711
Notice both answers equal 17,587,711
With that explanation out of the way, let's continue. Next, we take the number 17,587,711 and divide it by 2:
17,587,711 ÷ 2 = 8,793,855.5
If the quotient is a whole number, then 2 and 8,793,855.5 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 | 17,587,711 | |
-1 | -17,587,711 |
Now, we try dividing 17,587,711 by 3:
17,587,711 ÷ 3 = 5,862,570.3333
If the quotient is a whole number, then 3 and 5,862,570.3333 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 | 17,587,711 | |
-1 | -17,587,711 |
Let's try dividing by 4:
17,587,711 ÷ 4 = 4,396,927.75
If the quotient is a whole number, then 4 and 4,396,927.75 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 | 17,587,711 | |
-1 | 17,587,711 |
If you did it right, you will end up with this table:
1 | 19 | 925,669 | 17,587,711 |
-1 | -19 | -925,669 | -17,587,711 |
