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 1,623,415, 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 | 1,623,415 | |
| -1 | -1,623,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,623,415.
Example:
1 x 1,623,415 = 1,623,415
and
-1 x -1,623,415 = 1,623,415
Notice both answers equal 1,623,415
With that explanation out of the way, let's continue. Next, we take the number 1,623,415 and divide it by 2:
1,623,415 ÷ 2 = 811,707.5
If the quotient is a whole number, then 2 and 811,707.5 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 | 1,623,415 | |
| -1 | -1,623,415 |
Now, we try dividing 1,623,415 by 3:
1,623,415 ÷ 3 = 541,138.3333
If the quotient is a whole number, then 3 and 541,138.3333 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 | 1,623,415 | |
| -1 | -1,623,415 |
Let's try dividing by 4:
1,623,415 ÷ 4 = 405,853.75
If the quotient is a whole number, then 4 and 405,853.75 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 | 1,623,415 | |
| -1 | 1,623,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 71 | 85 | 269 | 355 | 1,207 | 1,345 | 4,573 | 6,035 | 19,099 | 22,865 | 95,495 | 324,683 | 1,623,415 |
| -1 | -5 | -17 | -71 | -85 | -269 | -355 | -1,207 | -1,345 | -4,573 | -6,035 | -19,099 | -22,865 | -95,495 | -324,683 | -1,623,415 |
