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 1,563,793, 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 | 1,563,793 | |
| -1 | -1,563,793 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,563,793.
Example:
1 x 1,563,793 = 1,563,793
and
-1 x -1,563,793 = 1,563,793
Notice both answers equal 1,563,793
With that explanation out of the way, let's continue. Next, we take the number 1,563,793 and divide it by 2:
1,563,793 ÷ 2 = 781,896.5
If the quotient is a whole number, then 2 and 781,896.5 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 | 1,563,793 | |
| -1 | -1,563,793 |
Now, we try dividing 1,563,793 by 3:
1,563,793 ÷ 3 = 521,264.3333
If the quotient is a whole number, then 3 and 521,264.3333 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 | 1,563,793 | |
| -1 | -1,563,793 |
Let's try dividing by 4:
1,563,793 ÷ 4 = 390,948.25
If the quotient is a whole number, then 4 and 390,948.25 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 | 1,563,793 | |
| -1 | 1,563,793 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 883 | 1,771 | 6,181 | 9,713 | 20,309 | 67,991 | 142,163 | 223,399 | 1,563,793 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -883 | -1,771 | -6,181 | -9,713 | -20,309 | -67,991 | -142,163 | -223,399 | -1,563,793 |
