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 7,928,041, 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 | 7,928,041 | |
-1 | -7,928,041 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,928,041.
Example:
1 x 7,928,041 = 7,928,041
and
-1 x -7,928,041 = 7,928,041
Notice both answers equal 7,928,041
With that explanation out of the way, let's continue. Next, we take the number 7,928,041 and divide it by 2:
7,928,041 ÷ 2 = 3,964,020.5
If the quotient is a whole number, then 2 and 3,964,020.5 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 | 7,928,041 | |
-1 | -7,928,041 |
Now, we try dividing 7,928,041 by 3:
7,928,041 ÷ 3 = 2,642,680.3333
If the quotient is a whole number, then 3 and 2,642,680.3333 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 | 7,928,041 | |
-1 | -7,928,041 |
Let's try dividing by 4:
7,928,041 ÷ 4 = 1,982,010.25
If the quotient is a whole number, then 4 and 1,982,010.25 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 | 7,928,041 | |
-1 | 7,928,041 |
If you did it right, you will end up with this table:
1 | 11 | 121 | 65,521 | 720,731 | 7,928,041 |
-1 | -11 | -121 | -65,521 | -720,731 | -7,928,041 |
