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 15,614,501, 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 | 15,614,501 | |
-1 | -15,614,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,614,501.
Example:
1 x 15,614,501 = 15,614,501
and
-1 x -15,614,501 = 15,614,501
Notice both answers equal 15,614,501
With that explanation out of the way, let's continue. Next, we take the number 15,614,501 and divide it by 2:
15,614,501 ÷ 2 = 7,807,250.5
If the quotient is a whole number, then 2 and 7,807,250.5 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 | 15,614,501 | |
-1 | -15,614,501 |
Now, we try dividing 15,614,501 by 3:
15,614,501 ÷ 3 = 5,204,833.6667
If the quotient is a whole number, then 3 and 5,204,833.6667 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 | 15,614,501 | |
-1 | -15,614,501 |
Let's try dividing by 4:
15,614,501 ÷ 4 = 3,903,625.25
If the quotient is a whole number, then 4 and 3,903,625.25 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 | 15,614,501 | |
-1 | 15,614,501 |
If you did it right, you will end up with this table:
1 | 7 | 2,230,643 | 15,614,501 |
-1 | -7 | -2,230,643 | -15,614,501 |
