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 26,521,819, 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 | 26,521,819 | |
-1 | -26,521,819 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,521,819.
Example:
1 x 26,521,819 = 26,521,819
and
-1 x -26,521,819 = 26,521,819
Notice both answers equal 26,521,819
With that explanation out of the way, let's continue. Next, we take the number 26,521,819 and divide it by 2:
26,521,819 ÷ 2 = 13,260,909.5
If the quotient is a whole number, then 2 and 13,260,909.5 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 | 26,521,819 | |
-1 | -26,521,819 |
Now, we try dividing 26,521,819 by 3:
26,521,819 ÷ 3 = 8,840,606.3333
If the quotient is a whole number, then 3 and 8,840,606.3333 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 | 26,521,819 | |
-1 | -26,521,819 |
Let's try dividing by 4:
26,521,819 ÷ 4 = 6,630,454.75
If the quotient is a whole number, then 4 and 6,630,454.75 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 | 26,521,819 | |
-1 | 26,521,819 |
If you did it right, you will end up with this table:
1 | 17 | 289 | 91,771 | 1,560,107 | 26,521,819 |
-1 | -17 | -289 | -91,771 | -1,560,107 | -26,521,819 |
