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 7,698,383, 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 | 7,698,383 | |
| -1 | -7,698,383 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,698,383.
Example:
1 x 7,698,383 = 7,698,383
and
-1 x -7,698,383 = 7,698,383
Notice both answers equal 7,698,383
With that explanation out of the way, let's continue. Next, we take the number 7,698,383 and divide it by 2:
7,698,383 ÷ 2 = 3,849,191.5
If the quotient is a whole number, then 2 and 3,849,191.5 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 | 7,698,383 | |
| -1 | -7,698,383 |
Now, we try dividing 7,698,383 by 3:
7,698,383 ÷ 3 = 2,566,127.6667
If the quotient is a whole number, then 3 and 2,566,127.6667 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 | 7,698,383 | |
| -1 | -7,698,383 |
Let's try dividing by 4:
7,698,383 ÷ 4 = 1,924,595.75
If the quotient is a whole number, then 4 and 1,924,595.75 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 | 7,698,383 | |
| -1 | 7,698,383 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 61 | 77 | 121 | 149 | 427 | 671 | 847 | 1,043 | 1,639 | 4,697 | 7,381 | 9,089 | 11,473 | 18,029 | 51,667 | 63,623 | 99,979 | 126,203 | 699,853 | 1,099,769 | 7,698,383 |
| -1 | -7 | -11 | -61 | -77 | -121 | -149 | -427 | -671 | -847 | -1,043 | -1,639 | -4,697 | -7,381 | -9,089 | -11,473 | -18,029 | -51,667 | -63,623 | -99,979 | -126,203 | -699,853 | -1,099,769 | -7,698,383 |
