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 602,501,245, 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 | 602,501,245 | |
| -1 | -602,501,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 602,501,245.
Example:
1 x 602,501,245 = 602,501,245
and
-1 x -602,501,245 = 602,501,245
Notice both answers equal 602,501,245
With that explanation out of the way, let's continue. Next, we take the number 602,501,245 and divide it by 2:
602,501,245 ÷ 2 = 301,250,622.5
If the quotient is a whole number, then 2 and 301,250,622.5 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 | 602,501,245 | |
| -1 | -602,501,245 |
Now, we try dividing 602,501,245 by 3:
602,501,245 ÷ 3 = 200,833,748.3333
If the quotient is a whole number, then 3 and 200,833,748.3333 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 | 602,501,245 | |
| -1 | -602,501,245 |
Let's try dividing by 4:
602,501,245 ÷ 4 = 150,625,311.25
If the quotient is a whole number, then 4 and 150,625,311.25 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 | 602,501,245 | |
| -1 | 602,501,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 977 | 4,253 | 4,885 | 21,265 | 28,333 | 123,337 | 141,665 | 616,685 | 4,155,181 | 20,775,905 | 120,500,249 | 602,501,245 |
| -1 | -5 | -29 | -145 | -977 | -4,253 | -4,885 | -21,265 | -28,333 | -123,337 | -141,665 | -616,685 | -4,155,181 | -20,775,905 | -120,500,249 | -602,501,245 |
