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 10,222,225, 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 | 10,222,225 | |
| -1 | -10,222,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,222,225.
Example:
1 x 10,222,225 = 10,222,225
and
-1 x -10,222,225 = 10,222,225
Notice both answers equal 10,222,225
With that explanation out of the way, let's continue. Next, we take the number 10,222,225 and divide it by 2:
10,222,225 ÷ 2 = 5,111,112.5
If the quotient is a whole number, then 2 and 5,111,112.5 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 | 10,222,225 | |
| -1 | -10,222,225 |
Now, we try dividing 10,222,225 by 3:
10,222,225 ÷ 3 = 3,407,408.3333
If the quotient is a whole number, then 3 and 3,407,408.3333 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 | 10,222,225 | |
| -1 | -10,222,225 |
Let's try dividing by 4:
10,222,225 ÷ 4 = 2,555,556.25
If the quotient is a whole number, then 4 and 2,555,556.25 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 | 10,222,225 | |
| -1 | 10,222,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 71 | 325 | 355 | 443 | 923 | 1,775 | 2,215 | 4,615 | 5,759 | 11,075 | 23,075 | 28,795 | 31,453 | 143,975 | 157,265 | 408,889 | 786,325 | 2,044,445 | 10,222,225 |
| -1 | -5 | -13 | -25 | -65 | -71 | -325 | -355 | -443 | -923 | -1,775 | -2,215 | -4,615 | -5,759 | -11,075 | -23,075 | -28,795 | -31,453 | -143,975 | -157,265 | -408,889 | -786,325 | -2,044,445 | -10,222,225 |
