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 450,251,011, 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 | 450,251,011 | |
| -1 | -450,251,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 450,251,011.
Example:
1 x 450,251,011 = 450,251,011
and
-1 x -450,251,011 = 450,251,011
Notice both answers equal 450,251,011
With that explanation out of the way, let's continue. Next, we take the number 450,251,011 and divide it by 2:
450,251,011 ÷ 2 = 225,125,505.5
If the quotient is a whole number, then 2 and 225,125,505.5 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 | 450,251,011 | |
| -1 | -450,251,011 |
Now, we try dividing 450,251,011 by 3:
450,251,011 ÷ 3 = 150,083,670.3333
If the quotient is a whole number, then 3 and 150,083,670.3333 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 | 450,251,011 | |
| -1 | -450,251,011 |
Let's try dividing by 4:
450,251,011 ÷ 4 = 112,562,752.75
If the quotient is a whole number, then 4 and 112,562,752.75 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 | 450,251,011 | |
| -1 | 450,251,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 97 | 173 | 679 | 1,211 | 3,833 | 16,781 | 26,831 | 117,467 | 371,801 | 663,109 | 2,602,607 | 4,641,763 | 64,321,573 | 450,251,011 |
| -1 | -7 | -97 | -173 | -679 | -1,211 | -3,833 | -16,781 | -26,831 | -117,467 | -371,801 | -663,109 | -2,602,607 | -4,641,763 | -64,321,573 | -450,251,011 |
