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 7,643,719, 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 | 7,643,719 | |
| -1 | -7,643,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,643,719.
Example:
1 x 7,643,719 = 7,643,719
and
-1 x -7,643,719 = 7,643,719
Notice both answers equal 7,643,719
With that explanation out of the way, let's continue. Next, we take the number 7,643,719 and divide it by 2:
7,643,719 ÷ 2 = 3,821,859.5
If the quotient is a whole number, then 2 and 3,821,859.5 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 | 7,643,719 | |
| -1 | -7,643,719 |
Now, we try dividing 7,643,719 by 3:
7,643,719 ÷ 3 = 2,547,906.3333
If the quotient is a whole number, then 3 and 2,547,906.3333 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 | 7,643,719 | |
| -1 | -7,643,719 |
Let's try dividing by 4:
7,643,719 ÷ 4 = 1,910,929.75
If the quotient is a whole number, then 4 and 1,910,929.75 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 | 7,643,719 | |
| -1 | 7,643,719 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 83 | 131 | 703 | 1,577 | 2,489 | 3,071 | 4,847 | 10,873 | 58,349 | 92,093 | 206,587 | 402,301 | 7,643,719 |
| -1 | -19 | -37 | -83 | -131 | -703 | -1,577 | -2,489 | -3,071 | -4,847 | -10,873 | -58,349 | -92,093 | -206,587 | -402,301 | -7,643,719 |
