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 75,803,303, 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 | 75,803,303 | |
| -1 | -75,803,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,803,303.
Example:
1 x 75,803,303 = 75,803,303
and
-1 x -75,803,303 = 75,803,303
Notice both answers equal 75,803,303
With that explanation out of the way, let's continue. Next, we take the number 75,803,303 and divide it by 2:
75,803,303 ÷ 2 = 37,901,651.5
If the quotient is a whole number, then 2 and 37,901,651.5 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 | 75,803,303 | |
| -1 | -75,803,303 |
Now, we try dividing 75,803,303 by 3:
75,803,303 ÷ 3 = 25,267,767.6667
If the quotient is a whole number, then 3 and 25,267,767.6667 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 | 75,803,303 | |
| -1 | -75,803,303 |
Let's try dividing by 4:
75,803,303 ÷ 4 = 18,950,825.75
If the quotient is a whole number, then 4 and 18,950,825.75 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 | 75,803,303 | |
| -1 | 75,803,303 |
If you did it right, you will end up with this table:
| 1 | 29 | 53 | 149 | 331 | 1,537 | 4,321 | 7,897 | 9,599 | 17,543 | 49,319 | 229,013 | 508,747 | 1,430,251 | 2,613,907 | 75,803,303 |
| -1 | -29 | -53 | -149 | -331 | -1,537 | -4,321 | -7,897 | -9,599 | -17,543 | -49,319 | -229,013 | -508,747 | -1,430,251 | -2,613,907 | -75,803,303 |
