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 1,624,315, 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 | 1,624,315 | |
| -1 | -1,624,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,624,315.
Example:
1 x 1,624,315 = 1,624,315
and
-1 x -1,624,315 = 1,624,315
Notice both answers equal 1,624,315
With that explanation out of the way, let's continue. Next, we take the number 1,624,315 and divide it by 2:
1,624,315 ÷ 2 = 812,157.5
If the quotient is a whole number, then 2 and 812,157.5 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 | 1,624,315 | |
| -1 | -1,624,315 |
Now, we try dividing 1,624,315 by 3:
1,624,315 ÷ 3 = 541,438.3333
If the quotient is a whole number, then 3 and 541,438.3333 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 | 1,624,315 | |
| -1 | -1,624,315 |
Let's try dividing by 4:
1,624,315 ÷ 4 = 406,078.75
If the quotient is a whole number, then 4 and 406,078.75 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 | 1,624,315 | |
| -1 | 1,624,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 4,219 | 21,095 | 29,533 | 46,409 | 147,665 | 232,045 | 324,863 | 1,624,315 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -4,219 | -21,095 | -29,533 | -46,409 | -147,665 | -232,045 | -324,863 | -1,624,315 |
