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 102,133,045, 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 | 102,133,045 | |
| -1 | -102,133,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,133,045.
Example:
1 x 102,133,045 = 102,133,045
and
-1 x -102,133,045 = 102,133,045
Notice both answers equal 102,133,045
With that explanation out of the way, let's continue. Next, we take the number 102,133,045 and divide it by 2:
102,133,045 ÷ 2 = 51,066,522.5
If the quotient is a whole number, then 2 and 51,066,522.5 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 | 102,133,045 | |
| -1 | -102,133,045 |
Now, we try dividing 102,133,045 by 3:
102,133,045 ÷ 3 = 34,044,348.3333
If the quotient is a whole number, then 3 and 34,044,348.3333 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 | 102,133,045 | |
| -1 | -102,133,045 |
Let's try dividing by 4:
102,133,045 ÷ 4 = 25,533,261.25
If the quotient is a whole number, then 4 and 25,533,261.25 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 | 102,133,045 | |
| -1 | 102,133,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,553 | 1,879 | 7,765 | 9,395 | 10,871 | 13,153 | 54,355 | 65,765 | 2,918,087 | 14,590,435 | 20,426,609 | 102,133,045 |
| -1 | -5 | -7 | -35 | -1,553 | -1,879 | -7,765 | -9,395 | -10,871 | -13,153 | -54,355 | -65,765 | -2,918,087 | -14,590,435 | -20,426,609 | -102,133,045 |
