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 75,255,103, 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 | 75,255,103 | |
| -1 | -75,255,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,255,103.
Example:
1 x 75,255,103 = 75,255,103
and
-1 x -75,255,103 = 75,255,103
Notice both answers equal 75,255,103
With that explanation out of the way, let's continue. Next, we take the number 75,255,103 and divide it by 2:
75,255,103 ÷ 2 = 37,627,551.5
If the quotient is a whole number, then 2 and 37,627,551.5 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 | 75,255,103 | |
| -1 | -75,255,103 |
Now, we try dividing 75,255,103 by 3:
75,255,103 ÷ 3 = 25,085,034.3333
If the quotient is a whole number, then 3 and 25,085,034.3333 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 | 75,255,103 | |
| -1 | -75,255,103 |
Let's try dividing by 4:
75,255,103 ÷ 4 = 18,813,775.75
If the quotient is a whole number, then 4 and 18,813,775.75 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 | 75,255,103 | |
| -1 | 75,255,103 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 121 | 161 | 253 | 847 | 1,771 | 2,783 | 3,863 | 19,481 | 27,041 | 42,493 | 88,849 | 297,451 | 467,423 | 621,943 | 977,339 | 3,271,961 | 6,841,373 | 10,750,729 | 75,255,103 |
| -1 | -7 | -11 | -23 | -77 | -121 | -161 | -253 | -847 | -1,771 | -2,783 | -3,863 | -19,481 | -27,041 | -42,493 | -88,849 | -297,451 | -467,423 | -621,943 | -977,339 | -3,271,961 | -6,841,373 | -10,750,729 | -75,255,103 |
