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 1,562,015, 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 | 1,562,015 | |
| -1 | -1,562,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,562,015.
Example:
1 x 1,562,015 = 1,562,015
and
-1 x -1,562,015 = 1,562,015
Notice both answers equal 1,562,015
With that explanation out of the way, let's continue. Next, we take the number 1,562,015 and divide it by 2:
1,562,015 ÷ 2 = 781,007.5
If the quotient is a whole number, then 2 and 781,007.5 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 | 1,562,015 | |
| -1 | -1,562,015 |
Now, we try dividing 1,562,015 by 3:
1,562,015 ÷ 3 = 520,671.6667
If the quotient is a whole number, then 3 and 520,671.6667 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 | 1,562,015 | |
| -1 | -1,562,015 |
Let's try dividing by 4:
1,562,015 ÷ 4 = 390,503.75
If the quotient is a whole number, then 4 and 390,503.75 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 | 1,562,015 | |
| -1 | 1,562,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 3,433 | 17,165 | 24,031 | 44,629 | 120,155 | 223,145 | 312,403 | 1,562,015 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -3,433 | -17,165 | -24,031 | -44,629 | -120,155 | -223,145 | -312,403 | -1,562,015 |
