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 10,202,225, 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 | 10,202,225 | |
| -1 | -10,202,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,202,225.
Example:
1 x 10,202,225 = 10,202,225
and
-1 x -10,202,225 = 10,202,225
Notice both answers equal 10,202,225
With that explanation out of the way, let's continue. Next, we take the number 10,202,225 and divide it by 2:
10,202,225 ÷ 2 = 5,101,112.5
If the quotient is a whole number, then 2 and 5,101,112.5 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 | 10,202,225 | |
| -1 | -10,202,225 |
Now, we try dividing 10,202,225 by 3:
10,202,225 ÷ 3 = 3,400,741.6667
If the quotient is a whole number, then 3 and 3,400,741.6667 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 | 10,202,225 | |
| -1 | -10,202,225 |
Let's try dividing by 4:
10,202,225 ÷ 4 = 2,550,556.25
If the quotient is a whole number, then 4 and 2,550,556.25 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 | 10,202,225 | |
| -1 | 10,202,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 1,265 | 1,613 | 6,325 | 8,065 | 17,743 | 37,099 | 40,325 | 88,715 | 185,495 | 408,089 | 443,575 | 927,475 | 2,040,445 | 10,202,225 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -1,265 | -1,613 | -6,325 | -8,065 | -17,743 | -37,099 | -40,325 | -88,715 | -185,495 | -408,089 | -443,575 | -927,475 | -2,040,445 | -10,202,225 |
