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 1,552,015, 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 | 1,552,015 | |
| -1 | -1,552,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,552,015.
Example:
1 x 1,552,015 = 1,552,015
and
-1 x -1,552,015 = 1,552,015
Notice both answers equal 1,552,015
With that explanation out of the way, let's continue. Next, we take the number 1,552,015 and divide it by 2:
1,552,015 ÷ 2 = 776,007.5
If the quotient is a whole number, then 2 and 776,007.5 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 | 1,552,015 | |
| -1 | -1,552,015 |
Now, we try dividing 1,552,015 by 3:
1,552,015 ÷ 3 = 517,338.3333
If the quotient is a whole number, then 3 and 517,338.3333 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 | 1,552,015 | |
| -1 | -1,552,015 |
Let's try dividing by 4:
1,552,015 ÷ 4 = 388,003.75
If the quotient is a whole number, then 4 and 388,003.75 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 | 1,552,015 | |
| -1 | 1,552,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 31 | 85 | 95 | 155 | 323 | 527 | 589 | 961 | 1,615 | 2,635 | 2,945 | 4,805 | 10,013 | 16,337 | 18,259 | 50,065 | 81,685 | 91,295 | 310,403 | 1,552,015 |
| -1 | -5 | -17 | -19 | -31 | -85 | -95 | -155 | -323 | -527 | -589 | -961 | -1,615 | -2,635 | -2,945 | -4,805 | -10,013 | -16,337 | -18,259 | -50,065 | -81,685 | -91,295 | -310,403 | -1,552,015 |
