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 1,368,211, 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 | 1,368,211 | |
| -1 | -1,368,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,368,211.
Example:
1 x 1,368,211 = 1,368,211
and
-1 x -1,368,211 = 1,368,211
Notice both answers equal 1,368,211
With that explanation out of the way, let's continue. Next, we take the number 1,368,211 and divide it by 2:
1,368,211 ÷ 2 = 684,105.5
If the quotient is a whole number, then 2 and 684,105.5 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 | 1,368,211 | |
| -1 | -1,368,211 |
Now, we try dividing 1,368,211 by 3:
1,368,211 ÷ 3 = 456,070.3333
If the quotient is a whole number, then 3 and 456,070.3333 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 | 1,368,211 | |
| -1 | -1,368,211 |
Let's try dividing by 4:
1,368,211 ÷ 4 = 342,052.75
If the quotient is a whole number, then 4 and 342,052.75 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 | 1,368,211 | |
| -1 | 1,368,211 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 41 | 151 | 221 | 533 | 697 | 1,963 | 2,567 | 6,191 | 9,061 | 33,371 | 80,483 | 105,247 | 1,368,211 |
| -1 | -13 | -17 | -41 | -151 | -221 | -533 | -697 | -1,963 | -2,567 | -6,191 | -9,061 | -33,371 | -80,483 | -105,247 | -1,368,211 |
