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 103,220,411, 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 | 103,220,411 | |
| -1 | -103,220,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,220,411.
Example:
1 x 103,220,411 = 103,220,411
and
-1 x -103,220,411 = 103,220,411
Notice both answers equal 103,220,411
With that explanation out of the way, let's continue. Next, we take the number 103,220,411 and divide it by 2:
103,220,411 ÷ 2 = 51,610,205.5
If the quotient is a whole number, then 2 and 51,610,205.5 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 | 103,220,411 | |
| -1 | -103,220,411 |
Now, we try dividing 103,220,411 by 3:
103,220,411 ÷ 3 = 34,406,803.6667
If the quotient is a whole number, then 3 and 34,406,803.6667 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 | 103,220,411 | |
| -1 | -103,220,411 |
Let's try dividing by 4:
103,220,411 ÷ 4 = 25,805,102.75
If the quotient is a whole number, then 4 and 25,805,102.75 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 | 103,220,411 | |
| -1 | 103,220,411 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 49 | 191 | 269 | 287 | 1,337 | 1,883 | 2,009 | 7,831 | 9,359 | 11,029 | 13,181 | 51,379 | 54,817 | 77,203 | 359,653 | 383,719 | 540,421 | 2,106,539 | 2,517,571 | 14,745,773 | 103,220,411 |
| -1 | -7 | -41 | -49 | -191 | -269 | -287 | -1,337 | -1,883 | -2,009 | -7,831 | -9,359 | -11,029 | -13,181 | -51,379 | -54,817 | -77,203 | -359,653 | -383,719 | -540,421 | -2,106,539 | -2,517,571 | -14,745,773 | -103,220,411 |
