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 1,403,215, 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 | 1,403,215 | |
| -1 | -1,403,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,403,215.
Example:
1 x 1,403,215 = 1,403,215
and
-1 x -1,403,215 = 1,403,215
Notice both answers equal 1,403,215
With that explanation out of the way, let's continue. Next, we take the number 1,403,215 and divide it by 2:
1,403,215 ÷ 2 = 701,607.5
If the quotient is a whole number, then 2 and 701,607.5 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 | 1,403,215 | |
| -1 | -1,403,215 |
Now, we try dividing 1,403,215 by 3:
1,403,215 ÷ 3 = 467,738.3333
If the quotient is a whole number, then 3 and 467,738.3333 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 | 1,403,215 | |
| -1 | -1,403,215 |
Let's try dividing by 4:
1,403,215 ÷ 4 = 350,803.75
If the quotient is a whole number, then 4 and 350,803.75 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 | 1,403,215 | |
| -1 | 1,403,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 823 | 1,705 | 4,115 | 9,053 | 25,513 | 45,265 | 127,565 | 280,643 | 1,403,215 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -823 | -1,705 | -4,115 | -9,053 | -25,513 | -45,265 | -127,565 | -280,643 | -1,403,215 |
