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 10,222,219, 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 | 10,222,219 | |
| -1 | -10,222,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,222,219.
Example:
1 x 10,222,219 = 10,222,219
and
-1 x -10,222,219 = 10,222,219
Notice both answers equal 10,222,219
With that explanation out of the way, let's continue. Next, we take the number 10,222,219 and divide it by 2:
10,222,219 ÷ 2 = 5,111,109.5
If the quotient is a whole number, then 2 and 5,111,109.5 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 | 10,222,219 | |
| -1 | -10,222,219 |
Now, we try dividing 10,222,219 by 3:
10,222,219 ÷ 3 = 3,407,406.3333
If the quotient is a whole number, then 3 and 3,407,406.3333 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 | 10,222,219 | |
| -1 | -10,222,219 |
Let's try dividing by 4:
10,222,219 ÷ 4 = 2,555,554.75
If the quotient is a whole number, then 4 and 2,555,554.75 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 | 10,222,219 | |
| -1 | 10,222,219 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 31 | 119 | 163 | 217 | 289 | 527 | 1,141 | 2,023 | 2,771 | 3,689 | 5,053 | 8,959 | 19,397 | 35,371 | 47,107 | 62,713 | 85,901 | 329,749 | 601,307 | 1,460,317 | 10,222,219 |
| -1 | -7 | -17 | -31 | -119 | -163 | -217 | -289 | -527 | -1,141 | -2,023 | -2,771 | -3,689 | -5,053 | -8,959 | -19,397 | -35,371 | -47,107 | -62,713 | -85,901 | -329,749 | -601,307 | -1,460,317 | -10,222,219 |
