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 102,353,245, 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 | 102,353,245 | |
| -1 | -102,353,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,353,245.
Example:
1 x 102,353,245 = 102,353,245
and
-1 x -102,353,245 = 102,353,245
Notice both answers equal 102,353,245
With that explanation out of the way, let's continue. Next, we take the number 102,353,245 and divide it by 2:
102,353,245 ÷ 2 = 51,176,622.5
If the quotient is a whole number, then 2 and 51,176,622.5 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 | 102,353,245 | |
| -1 | -102,353,245 |
Now, we try dividing 102,353,245 by 3:
102,353,245 ÷ 3 = 34,117,748.3333
If the quotient is a whole number, then 3 and 34,117,748.3333 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 | 102,353,245 | |
| -1 | -102,353,245 |
Let's try dividing by 4:
102,353,245 ÷ 4 = 25,588,311.25
If the quotient is a whole number, then 4 and 25,588,311.25 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 | 102,353,245 | |
| -1 | 102,353,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 355 | 401 | 719 | 2,005 | 3,595 | 28,471 | 51,049 | 142,355 | 255,245 | 288,319 | 1,441,595 | 20,470,649 | 102,353,245 |
| -1 | -5 | -71 | -355 | -401 | -719 | -2,005 | -3,595 | -28,471 | -51,049 | -142,355 | -255,245 | -288,319 | -1,441,595 | -20,470,649 | -102,353,245 |
