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 6,220,165, 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 | 6,220,165 | |
| -1 | -6,220,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,220,165.
Example:
1 x 6,220,165 = 6,220,165
and
-1 x -6,220,165 = 6,220,165
Notice both answers equal 6,220,165
With that explanation out of the way, let's continue. Next, we take the number 6,220,165 and divide it by 2:
6,220,165 ÷ 2 = 3,110,082.5
If the quotient is a whole number, then 2 and 3,110,082.5 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 | 6,220,165 | |
| -1 | -6,220,165 |
Now, we try dividing 6,220,165 by 3:
6,220,165 ÷ 3 = 2,073,388.3333
If the quotient is a whole number, then 3 and 2,073,388.3333 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 | 6,220,165 | |
| -1 | -6,220,165 |
Let's try dividing by 4:
6,220,165 ÷ 4 = 1,555,041.25
If the quotient is a whole number, then 4 and 1,555,041.25 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 | 6,220,165 | |
| -1 | 6,220,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 4,133 | 20,665 | 28,931 | 144,655 | 177,719 | 888,595 | 1,244,033 | 6,220,165 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -4,133 | -20,665 | -28,931 | -144,655 | -177,719 | -888,595 | -1,244,033 | -6,220,165 |
