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 33,143,275, 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 | 33,143,275 | |
| -1 | -33,143,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,143,275.
Example:
1 x 33,143,275 = 33,143,275
and
-1 x -33,143,275 = 33,143,275
Notice both answers equal 33,143,275
With that explanation out of the way, let's continue. Next, we take the number 33,143,275 and divide it by 2:
33,143,275 ÷ 2 = 16,571,637.5
If the quotient is a whole number, then 2 and 16,571,637.5 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 | 33,143,275 | |
| -1 | -33,143,275 |
Now, we try dividing 33,143,275 by 3:
33,143,275 ÷ 3 = 11,047,758.3333
If the quotient is a whole number, then 3 and 11,047,758.3333 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 | 33,143,275 | |
| -1 | -33,143,275 |
Let's try dividing by 4:
33,143,275 ÷ 4 = 8,285,818.75
If the quotient is a whole number, then 4 and 8,285,818.75 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 | 33,143,275 | |
| -1 | 33,143,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 191 | 275 | 631 | 955 | 2,101 | 3,155 | 4,775 | 6,941 | 10,505 | 15,775 | 34,705 | 52,525 | 120,521 | 173,525 | 602,605 | 1,325,731 | 3,013,025 | 6,628,655 | 33,143,275 |
| -1 | -5 | -11 | -25 | -55 | -191 | -275 | -631 | -955 | -2,101 | -3,155 | -4,775 | -6,941 | -10,505 | -15,775 | -34,705 | -52,525 | -120,521 | -173,525 | -602,605 | -1,325,731 | -3,013,025 | -6,628,655 | -33,143,275 |
