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 1,340,003, 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 | 1,340,003 | |
| -1 | -1,340,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,340,003.
Example:
1 x 1,340,003 = 1,340,003
and
-1 x -1,340,003 = 1,340,003
Notice both answers equal 1,340,003
With that explanation out of the way, let's continue. Next, we take the number 1,340,003 and divide it by 2:
1,340,003 ÷ 2 = 670,001.5
If the quotient is a whole number, then 2 and 670,001.5 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 | 1,340,003 | |
| -1 | -1,340,003 |
Now, we try dividing 1,340,003 by 3:
1,340,003 ÷ 3 = 446,667.6667
If the quotient is a whole number, then 3 and 446,667.6667 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 | 1,340,003 | |
| -1 | -1,340,003 |
Let's try dividing by 4:
1,340,003 ÷ 4 = 335,000.75
If the quotient is a whole number, then 4 and 335,000.75 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 | 1,340,003 | |
| -1 | 1,340,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 41 | 49 | 161 | 203 | 287 | 667 | 943 | 1,127 | 1,189 | 1,421 | 2,009 | 4,669 | 6,601 | 8,323 | 27,347 | 32,683 | 46,207 | 58,261 | 191,429 | 1,340,003 |
| -1 | -7 | -23 | -29 | -41 | -49 | -161 | -203 | -287 | -667 | -943 | -1,127 | -1,189 | -1,421 | -2,009 | -4,669 | -6,601 | -8,323 | -27,347 | -32,683 | -46,207 | -58,261 | -191,429 | -1,340,003 |
