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 102,147,347, 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 | 102,147,347 | |
| -1 | -102,147,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,147,347.
Example:
1 x 102,147,347 = 102,147,347
and
-1 x -102,147,347 = 102,147,347
Notice both answers equal 102,147,347
With that explanation out of the way, let's continue. Next, we take the number 102,147,347 and divide it by 2:
102,147,347 ÷ 2 = 51,073,673.5
If the quotient is a whole number, then 2 and 51,073,673.5 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 | 102,147,347 | |
| -1 | -102,147,347 |
Now, we try dividing 102,147,347 by 3:
102,147,347 ÷ 3 = 34,049,115.6667
If the quotient is a whole number, then 3 and 34,049,115.6667 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 | 102,147,347 | |
| -1 | -102,147,347 |
Let's try dividing by 4:
102,147,347 ÷ 4 = 25,536,836.75
If the quotient is a whole number, then 4 and 25,536,836.75 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 | 102,147,347 | |
| -1 | 102,147,347 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 139 | 359 | 2,047 | 3,197 | 8,257 | 12,371 | 31,951 | 49,901 | 284,533 | 734,873 | 1,147,723 | 4,441,189 | 102,147,347 |
| -1 | -23 | -89 | -139 | -359 | -2,047 | -3,197 | -8,257 | -12,371 | -31,951 | -49,901 | -284,533 | -734,873 | -1,147,723 | -4,441,189 | -102,147,347 |
