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 102,133,213, 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 | 102,133,213 | |
| -1 | -102,133,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,133,213.
Example:
1 x 102,133,213 = 102,133,213
and
-1 x -102,133,213 = 102,133,213
Notice both answers equal 102,133,213
With that explanation out of the way, let's continue. Next, we take the number 102,133,213 and divide it by 2:
102,133,213 ÷ 2 = 51,066,606.5
If the quotient is a whole number, then 2 and 51,066,606.5 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 | 102,133,213 | |
| -1 | -102,133,213 |
Now, we try dividing 102,133,213 by 3:
102,133,213 ÷ 3 = 34,044,404.3333
If the quotient is a whole number, then 3 and 34,044,404.3333 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 | 102,133,213 | |
| -1 | -102,133,213 |
Let's try dividing by 4:
102,133,213 ÷ 4 = 25,533,303.25
If the quotient is a whole number, then 4 and 25,533,303.25 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 | 102,133,213 | |
| -1 | 102,133,213 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 91 | 301 | 559 | 607 | 1,849 | 3,913 | 4,249 | 7,891 | 12,943 | 24,037 | 26,101 | 55,237 | 168,259 | 182,707 | 339,313 | 1,122,343 | 2,375,191 | 7,856,401 | 14,590,459 | 102,133,213 |
| -1 | -7 | -13 | -43 | -91 | -301 | -559 | -607 | -1,849 | -3,913 | -4,249 | -7,891 | -12,943 | -24,037 | -26,101 | -55,237 | -168,259 | -182,707 | -339,313 | -1,122,343 | -2,375,191 | -7,856,401 | -14,590,459 | -102,133,213 |
