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 3,120,565, 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 | 3,120,565 | |
| -1 | -3,120,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,120,565.
Example:
1 x 3,120,565 = 3,120,565
and
-1 x -3,120,565 = 3,120,565
Notice both answers equal 3,120,565
With that explanation out of the way, let's continue. Next, we take the number 3,120,565 and divide it by 2:
3,120,565 ÷ 2 = 1,560,282.5
If the quotient is a whole number, then 2 and 1,560,282.5 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 | 3,120,565 | |
| -1 | -3,120,565 |
Now, we try dividing 3,120,565 by 3:
3,120,565 ÷ 3 = 1,040,188.3333
If the quotient is a whole number, then 3 and 1,040,188.3333 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 | 3,120,565 | |
| -1 | -3,120,565 |
Let's try dividing by 4:
3,120,565 ÷ 4 = 780,141.25
If the quotient is a whole number, then 4 and 780,141.25 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 | 3,120,565 | |
| -1 | 3,120,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 49 | 235 | 245 | 271 | 329 | 1,355 | 1,645 | 1,897 | 2,303 | 9,485 | 11,515 | 12,737 | 13,279 | 63,685 | 66,395 | 89,159 | 445,795 | 624,113 | 3,120,565 |
| -1 | -5 | -7 | -35 | -47 | -49 | -235 | -245 | -271 | -329 | -1,355 | -1,645 | -1,897 | -2,303 | -9,485 | -11,515 | -12,737 | -13,279 | -63,685 | -66,395 | -89,159 | -445,795 | -624,113 | -3,120,565 |
