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 103,011,503, 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 | 103,011,503 | |
| -1 | -103,011,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,011,503.
Example:
1 x 103,011,503 = 103,011,503
and
-1 x -103,011,503 = 103,011,503
Notice both answers equal 103,011,503
With that explanation out of the way, let's continue. Next, we take the number 103,011,503 and divide it by 2:
103,011,503 ÷ 2 = 51,505,751.5
If the quotient is a whole number, then 2 and 51,505,751.5 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 | 103,011,503 | |
| -1 | -103,011,503 |
Now, we try dividing 103,011,503 by 3:
103,011,503 ÷ 3 = 34,337,167.6667
If the quotient is a whole number, then 3 and 34,337,167.6667 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 | 103,011,503 | |
| -1 | -103,011,503 |
Let's try dividing by 4:
103,011,503 ÷ 4 = 25,752,875.75
If the quotient is a whole number, then 4 and 25,752,875.75 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 | 103,011,503 | |
| -1 | 103,011,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 331 | 1,933 | 2,317 | 7,613 | 13,531 | 44,459 | 53,291 | 311,213 | 639,823 | 4,478,761 | 14,715,929 | 103,011,503 |
| -1 | -7 | -23 | -161 | -331 | -1,933 | -2,317 | -7,613 | -13,531 | -44,459 | -53,291 | -311,213 | -639,823 | -4,478,761 | -14,715,929 | -103,011,503 |
