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 7,224,395, 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 | 7,224,395 | |
| -1 | -7,224,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,224,395.
Example:
1 x 7,224,395 = 7,224,395
and
-1 x -7,224,395 = 7,224,395
Notice both answers equal 7,224,395
With that explanation out of the way, let's continue. Next, we take the number 7,224,395 and divide it by 2:
7,224,395 ÷ 2 = 3,612,197.5
If the quotient is a whole number, then 2 and 3,612,197.5 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 | 7,224,395 | |
| -1 | -7,224,395 |
Now, we try dividing 7,224,395 by 3:
7,224,395 ÷ 3 = 2,408,131.6667
If the quotient is a whole number, then 3 and 2,408,131.6667 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 | 7,224,395 | |
| -1 | -7,224,395 |
Let's try dividing by 4:
7,224,395 ÷ 4 = 1,806,098.75
If the quotient is a whole number, then 4 and 1,806,098.75 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 | 7,224,395 | |
| -1 | 7,224,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 127 | 155 | 367 | 635 | 1,835 | 3,937 | 11,377 | 19,685 | 46,609 | 56,885 | 233,045 | 1,444,879 | 7,224,395 |
| -1 | -5 | -31 | -127 | -155 | -367 | -635 | -1,835 | -3,937 | -11,377 | -19,685 | -46,609 | -56,885 | -233,045 | -1,444,879 | -7,224,395 |
