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 103,220,435, 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 | 103,220,435 | |
| -1 | -103,220,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,220,435.
Example:
1 x 103,220,435 = 103,220,435
and
-1 x -103,220,435 = 103,220,435
Notice both answers equal 103,220,435
With that explanation out of the way, let's continue. Next, we take the number 103,220,435 and divide it by 2:
103,220,435 ÷ 2 = 51,610,217.5
If the quotient is a whole number, then 2 and 51,610,217.5 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 | 103,220,435 | |
| -1 | -103,220,435 |
Now, we try dividing 103,220,435 by 3:
103,220,435 ÷ 3 = 34,406,811.6667
If the quotient is a whole number, then 3 and 34,406,811.6667 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 | 103,220,435 | |
| -1 | -103,220,435 |
Let's try dividing by 4:
103,220,435 ÷ 4 = 25,805,108.75
If the quotient is a whole number, then 4 and 25,805,108.75 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 | 103,220,435 | |
| -1 | 103,220,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 157 | 785 | 3,611 | 5,717 | 18,055 | 28,585 | 131,491 | 657,455 | 897,569 | 4,487,845 | 20,644,087 | 103,220,435 |
| -1 | -5 | -23 | -115 | -157 | -785 | -3,611 | -5,717 | -18,055 | -28,585 | -131,491 | -657,455 | -897,569 | -4,487,845 | -20,644,087 | -103,220,435 |
