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 13,647,215, 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 | 13,647,215 | |
-1 | -13,647,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,647,215.
Example:
1 x 13,647,215 = 13,647,215
and
-1 x -13,647,215 = 13,647,215
Notice both answers equal 13,647,215
With that explanation out of the way, let's continue. Next, we take the number 13,647,215 and divide it by 2:
13,647,215 ÷ 2 = 6,823,607.5
If the quotient is a whole number, then 2 and 6,823,607.5 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 | 13,647,215 | |
-1 | -13,647,215 |
Now, we try dividing 13,647,215 by 3:
13,647,215 ÷ 3 = 4,549,071.6667
If the quotient is a whole number, then 3 and 4,549,071.6667 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 | 13,647,215 | |
-1 | -13,647,215 |
Let's try dividing by 4:
13,647,215 ÷ 4 = 3,411,803.75
If the quotient is a whole number, then 4 and 3,411,803.75 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 | 13,647,215 | |
-1 | 13,647,215 |
If you did it right, you will end up with this table:
1 | 5 | 2,729,443 | 13,647,215 |
-1 | -5 | -2,729,443 | -13,647,215 |
