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 178,016,503, 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 | 178,016,503 | |
| -1 | -178,016,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 178,016,503.
Example:
1 x 178,016,503 = 178,016,503
and
-1 x -178,016,503 = 178,016,503
Notice both answers equal 178,016,503
With that explanation out of the way, let's continue. Next, we take the number 178,016,503 and divide it by 2:
178,016,503 ÷ 2 = 89,008,251.5
If the quotient is a whole number, then 2 and 89,008,251.5 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 | 178,016,503 | |
| -1 | -178,016,503 |
Now, we try dividing 178,016,503 by 3:
178,016,503 ÷ 3 = 59,338,834.3333
If the quotient is a whole number, then 3 and 59,338,834.3333 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 | 178,016,503 | |
| -1 | -178,016,503 |
Let's try dividing by 4:
178,016,503 ÷ 4 = 44,504,125.75
If the quotient is a whole number, then 4 and 44,504,125.75 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 | 178,016,503 | |
| -1 | 178,016,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 839 | 1,783 | 5,873 | 12,481 | 14,263 | 30,311 | 99,841 | 212,177 | 1,495,937 | 10,471,559 | 25,430,929 | 178,016,503 |
| -1 | -7 | -17 | -119 | -839 | -1,783 | -5,873 | -12,481 | -14,263 | -30,311 | -99,841 | -212,177 | -1,495,937 | -10,471,559 | -25,430,929 | -178,016,503 |
