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 145,223,503, 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 | 145,223,503 | |
| -1 | -145,223,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,223,503.
Example:
1 x 145,223,503 = 145,223,503
and
-1 x -145,223,503 = 145,223,503
Notice both answers equal 145,223,503
With that explanation out of the way, let's continue. Next, we take the number 145,223,503 and divide it by 2:
145,223,503 ÷ 2 = 72,611,751.5
If the quotient is a whole number, then 2 and 72,611,751.5 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 | 145,223,503 | |
| -1 | -145,223,503 |
Now, we try dividing 145,223,503 by 3:
145,223,503 ÷ 3 = 48,407,834.3333
If the quotient is a whole number, then 3 and 48,407,834.3333 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 | 145,223,503 | |
| -1 | -145,223,503 |
Let's try dividing by 4:
145,223,503 ÷ 4 = 36,305,875.75
If the quotient is a whole number, then 4 and 36,305,875.75 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 | 145,223,503 | |
| -1 | 145,223,503 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 107 | 493 | 1,819 | 2,753 | 3,103 | 46,801 | 52,751 | 79,837 | 294,571 | 1,357,229 | 5,007,707 | 8,542,559 | 145,223,503 |
| -1 | -17 | -29 | -107 | -493 | -1,819 | -2,753 | -3,103 | -46,801 | -52,751 | -79,837 | -294,571 | -1,357,229 | -5,007,707 | -8,542,559 | -145,223,503 |
