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 102,122,137, 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 | 102,122,137 | |
| -1 | -102,122,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,122,137.
Example:
1 x 102,122,137 = 102,122,137
and
-1 x -102,122,137 = 102,122,137
Notice both answers equal 102,122,137
With that explanation out of the way, let's continue. Next, we take the number 102,122,137 and divide it by 2:
102,122,137 ÷ 2 = 51,061,068.5
If the quotient is a whole number, then 2 and 51,061,068.5 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 | 102,122,137 | |
| -1 | -102,122,137 |
Now, we try dividing 102,122,137 by 3:
102,122,137 ÷ 3 = 34,040,712.3333
If the quotient is a whole number, then 3 and 34,040,712.3333 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 | 102,122,137 | |
| -1 | -102,122,137 |
Let's try dividing by 4:
102,122,137 ÷ 4 = 25,530,534.25
If the quotient is a whole number, then 4 and 25,530,534.25 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 | 102,122,137 | |
| -1 | 102,122,137 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 67 | 169 | 311 | 377 | 871 | 1,943 | 4,043 | 4,901 | 9,019 | 11,323 | 20,837 | 25,259 | 52,559 | 117,247 | 270,881 | 328,367 | 604,273 | 1,524,211 | 3,521,453 | 7,855,549 | 102,122,137 |
| -1 | -13 | -29 | -67 | -169 | -311 | -377 | -871 | -1,943 | -4,043 | -4,901 | -9,019 | -11,323 | -20,837 | -25,259 | -52,559 | -117,247 | -270,881 | -328,367 | -604,273 | -1,524,211 | -3,521,453 | -7,855,549 | -102,122,137 |
