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 3,620,269, 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 | 3,620,269 | |
| -1 | -3,620,269 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,620,269.
Example:
1 x 3,620,269 = 3,620,269
and
-1 x -3,620,269 = 3,620,269
Notice both answers equal 3,620,269
With that explanation out of the way, let's continue. Next, we take the number 3,620,269 and divide it by 2:
3,620,269 ÷ 2 = 1,810,134.5
If the quotient is a whole number, then 2 and 1,810,134.5 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 | 3,620,269 | |
| -1 | -3,620,269 |
Now, we try dividing 3,620,269 by 3:
3,620,269 ÷ 3 = 1,206,756.3333
If the quotient is a whole number, then 3 and 1,206,756.3333 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 | 3,620,269 | |
| -1 | -3,620,269 |
Let's try dividing by 4:
3,620,269 ÷ 4 = 905,067.25
If the quotient is a whole number, then 4 and 905,067.25 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 | 3,620,269 | |
| -1 | 3,620,269 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 47 | 197 | 391 | 799 | 1,081 | 3,349 | 4,531 | 9,259 | 18,377 | 77,027 | 157,403 | 212,957 | 3,620,269 |
| -1 | -17 | -23 | -47 | -197 | -391 | -799 | -1,081 | -3,349 | -4,531 | -9,259 | -18,377 | -77,027 | -157,403 | -212,957 | -3,620,269 |
