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 75,003,227, 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 | 75,003,227 | |
| -1 | -75,003,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,003,227.
Example:
1 x 75,003,227 = 75,003,227
and
-1 x -75,003,227 = 75,003,227
Notice both answers equal 75,003,227
With that explanation out of the way, let's continue. Next, we take the number 75,003,227 and divide it by 2:
75,003,227 ÷ 2 = 37,501,613.5
If the quotient is a whole number, then 2 and 37,501,613.5 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 | 75,003,227 | |
| -1 | -75,003,227 |
Now, we try dividing 75,003,227 by 3:
75,003,227 ÷ 3 = 25,001,075.6667
If the quotient is a whole number, then 3 and 25,001,075.6667 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 | 75,003,227 | |
| -1 | -75,003,227 |
Let's try dividing by 4:
75,003,227 ÷ 4 = 18,750,806.75
If the quotient is a whole number, then 4 and 18,750,806.75 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 | 75,003,227 | |
| -1 | 75,003,227 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 109 | 533 | 1,291 | 1,417 | 4,469 | 16,783 | 52,931 | 58,097 | 140,719 | 688,103 | 1,829,347 | 5,769,479 | 75,003,227 |
| -1 | -13 | -41 | -109 | -533 | -1,291 | -1,417 | -4,469 | -16,783 | -52,931 | -58,097 | -140,719 | -688,103 | -1,829,347 | -5,769,479 | -75,003,227 |
