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 7,214,851, 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 | 7,214,851 | |
| -1 | -7,214,851 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,214,851.
Example:
1 x 7,214,851 = 7,214,851
and
-1 x -7,214,851 = 7,214,851
Notice both answers equal 7,214,851
With that explanation out of the way, let's continue. Next, we take the number 7,214,851 and divide it by 2:
7,214,851 ÷ 2 = 3,607,425.5
If the quotient is a whole number, then 2 and 3,607,425.5 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 | 7,214,851 | |
| -1 | -7,214,851 |
Now, we try dividing 7,214,851 by 3:
7,214,851 ÷ 3 = 2,404,950.3333
If the quotient is a whole number, then 3 and 2,404,950.3333 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 | 7,214,851 | |
| -1 | -7,214,851 |
Let's try dividing by 4:
7,214,851 ÷ 4 = 1,803,712.75
If the quotient is a whole number, then 4 and 1,803,712.75 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 | 7,214,851 | |
| -1 | 7,214,851 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 3,191 | 22,337 | 54,247 | 60,629 | 379,729 | 424,403 | 1,030,693 | 7,214,851 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -3,191 | -22,337 | -54,247 | -60,629 | -379,729 | -424,403 | -1,030,693 | -7,214,851 |
