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 102,052,055, 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 | 102,052,055 | |
| -1 | -102,052,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,052,055.
Example:
1 x 102,052,055 = 102,052,055
and
-1 x -102,052,055 = 102,052,055
Notice both answers equal 102,052,055
With that explanation out of the way, let's continue. Next, we take the number 102,052,055 and divide it by 2:
102,052,055 ÷ 2 = 51,026,027.5
If the quotient is a whole number, then 2 and 51,026,027.5 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 | 102,052,055 | |
| -1 | -102,052,055 |
Now, we try dividing 102,052,055 by 3:
102,052,055 ÷ 3 = 34,017,351.6667
If the quotient is a whole number, then 3 and 34,017,351.6667 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 | 102,052,055 | |
| -1 | -102,052,055 |
Let's try dividing by 4:
102,052,055 ÷ 4 = 25,513,013.75
If the quotient is a whole number, then 4 and 25,513,013.75 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 | 102,052,055 | |
| -1 | 102,052,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 67 | 245 | 335 | 469 | 2,345 | 3,283 | 6,217 | 16,415 | 31,085 | 43,519 | 217,595 | 304,633 | 416,539 | 1,523,165 | 2,082,695 | 2,915,773 | 14,578,865 | 20,410,411 | 102,052,055 |
| -1 | -5 | -7 | -35 | -49 | -67 | -245 | -335 | -469 | -2,345 | -3,283 | -6,217 | -16,415 | -31,085 | -43,519 | -217,595 | -304,633 | -416,539 | -1,523,165 | -2,082,695 | -2,915,773 | -14,578,865 | -20,410,411 | -102,052,055 |
