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 7,378,499, 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 | 7,378,499 | |
| -1 | -7,378,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,378,499.
Example:
1 x 7,378,499 = 7,378,499
and
-1 x -7,378,499 = 7,378,499
Notice both answers equal 7,378,499
With that explanation out of the way, let's continue. Next, we take the number 7,378,499 and divide it by 2:
7,378,499 ÷ 2 = 3,689,249.5
If the quotient is a whole number, then 2 and 3,689,249.5 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 | 7,378,499 | |
| -1 | -7,378,499 |
Now, we try dividing 7,378,499 by 3:
7,378,499 ÷ 3 = 2,459,499.6667
If the quotient is a whole number, then 3 and 2,459,499.6667 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 | 7,378,499 | |
| -1 | -7,378,499 |
Let's try dividing by 4:
7,378,499 ÷ 4 = 1,844,624.75
If the quotient is a whole number, then 4 and 1,844,624.75 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 | 7,378,499 | |
| -1 | 7,378,499 |
If you did it right, you will end up with this table:
| 1 | 29 | 43 | 61 | 97 | 1,247 | 1,769 | 2,623 | 2,813 | 4,171 | 5,917 | 76,067 | 120,959 | 171,593 | 254,431 | 7,378,499 |
| -1 | -29 | -43 | -61 | -97 | -1,247 | -1,769 | -2,623 | -2,813 | -4,171 | -5,917 | -76,067 | -120,959 | -171,593 | -254,431 | -7,378,499 |
