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 303,126,415, 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 | 303,126,415 | |
| -1 | -303,126,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,126,415.
Example:
1 x 303,126,415 = 303,126,415
and
-1 x -303,126,415 = 303,126,415
Notice both answers equal 303,126,415
With that explanation out of the way, let's continue. Next, we take the number 303,126,415 and divide it by 2:
303,126,415 ÷ 2 = 151,563,207.5
If the quotient is a whole number, then 2 and 151,563,207.5 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 | 303,126,415 | |
| -1 | -303,126,415 |
Now, we try dividing 303,126,415 by 3:
303,126,415 ÷ 3 = 101,042,138.3333
If the quotient is a whole number, then 3 and 101,042,138.3333 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 | 303,126,415 | |
| -1 | -303,126,415 |
Let's try dividing by 4:
303,126,415 ÷ 4 = 75,781,603.75
If the quotient is a whole number, then 4 and 75,781,603.75 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 | 303,126,415 | |
| -1 | 303,126,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 313 | 1,565 | 6,679 | 9,077 | 33,395 | 45,385 | 193,691 | 968,455 | 2,090,527 | 10,452,635 | 60,625,283 | 303,126,415 |
| -1 | -5 | -29 | -145 | -313 | -1,565 | -6,679 | -9,077 | -33,395 | -45,385 | -193,691 | -968,455 | -2,090,527 | -10,452,635 | -60,625,283 | -303,126,415 |
