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 200,501,245, 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 | 200,501,245 | |
| -1 | -200,501,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,501,245.
Example:
1 x 200,501,245 = 200,501,245
and
-1 x -200,501,245 = 200,501,245
Notice both answers equal 200,501,245
With that explanation out of the way, let's continue. Next, we take the number 200,501,245 and divide it by 2:
200,501,245 ÷ 2 = 100,250,622.5
If the quotient is a whole number, then 2 and 100,250,622.5 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 | 200,501,245 | |
| -1 | -200,501,245 |
Now, we try dividing 200,501,245 by 3:
200,501,245 ÷ 3 = 66,833,748.3333
If the quotient is a whole number, then 3 and 66,833,748.3333 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 | 200,501,245 | |
| -1 | -200,501,245 |
Let's try dividing by 4:
200,501,245 ÷ 4 = 50,125,311.25
If the quotient is a whole number, then 4 and 50,125,311.25 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 | 200,501,245 | |
| -1 | 200,501,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 139 | 695 | 973 | 4,865 | 41,213 | 206,065 | 288,491 | 1,442,455 | 5,728,607 | 28,643,035 | 40,100,249 | 200,501,245 |
| -1 | -5 | -7 | -35 | -139 | -695 | -973 | -4,865 | -41,213 | -206,065 | -288,491 | -1,442,455 | -5,728,607 | -28,643,035 | -40,100,249 | -200,501,245 |
