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 1,021,111, 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 | 1,021,111 | |
| -1 | -1,021,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,021,111.
Example:
1 x 1,021,111 = 1,021,111
and
-1 x -1,021,111 = 1,021,111
Notice both answers equal 1,021,111
With that explanation out of the way, let's continue. Next, we take the number 1,021,111 and divide it by 2:
1,021,111 ÷ 2 = 510,555.5
If the quotient is a whole number, then 2 and 510,555.5 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 | 1,021,111 | |
| -1 | -1,021,111 |
Now, we try dividing 1,021,111 by 3:
1,021,111 ÷ 3 = 340,370.3333
If the quotient is a whole number, then 3 and 340,370.3333 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 | 1,021,111 | |
| -1 | -1,021,111 |
Let's try dividing by 4:
1,021,111 ÷ 4 = 255,277.75
If the quotient is a whole number, then 4 and 255,277.75 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 | 1,021,111 | |
| -1 | 1,021,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 229 | 343 | 637 | 1,603 | 2,977 | 4,459 | 11,221 | 20,839 | 78,547 | 145,873 | 1,021,111 |
| -1 | -7 | -13 | -49 | -91 | -229 | -343 | -637 | -1,603 | -2,977 | -4,459 | -11,221 | -20,839 | -78,547 | -145,873 | -1,021,111 |
