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 38,515,529, 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 | 38,515,529 | |
-1 | -38,515,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,515,529.
Example:
1 x 38,515,529 = 38,515,529
and
-1 x -38,515,529 = 38,515,529
Notice both answers equal 38,515,529
With that explanation out of the way, let's continue. Next, we take the number 38,515,529 and divide it by 2:
38,515,529 ÷ 2 = 19,257,764.5
If the quotient is a whole number, then 2 and 19,257,764.5 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 | 38,515,529 | |
-1 | -38,515,529 |
Now, we try dividing 38,515,529 by 3:
38,515,529 ÷ 3 = 12,838,509.6667
If the quotient is a whole number, then 3 and 12,838,509.6667 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 | 38,515,529 | |
-1 | -38,515,529 |
Let's try dividing by 4:
38,515,529 ÷ 4 = 9,628,882.25
If the quotient is a whole number, then 4 and 9,628,882.25 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 | 38,515,529 | |
-1 | 38,515,529 |
If you did it right, you will end up with this table:
1 | 13 | 2,962,733 | 38,515,529 |
-1 | -13 | -2,962,733 | -38,515,529 |
