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 437,716,435, 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 | 437,716,435 | |
| -1 | -437,716,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 437,716,435.
Example:
1 x 437,716,435 = 437,716,435
and
-1 x -437,716,435 = 437,716,435
Notice both answers equal 437,716,435
With that explanation out of the way, let's continue. Next, we take the number 437,716,435 and divide it by 2:
437,716,435 ÷ 2 = 218,858,217.5
If the quotient is a whole number, then 2 and 218,858,217.5 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 | 437,716,435 | |
| -1 | -437,716,435 |
Now, we try dividing 437,716,435 by 3:
437,716,435 ÷ 3 = 145,905,478.3333
If the quotient is a whole number, then 3 and 145,905,478.3333 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 | 437,716,435 | |
| -1 | -437,716,435 |
Let's try dividing by 4:
437,716,435 ÷ 4 = 109,429,108.75
If the quotient is a whole number, then 4 and 109,429,108.75 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 | 437,716,435 | |
| -1 | 437,716,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 2,015 | 217,229 | 1,086,145 | 2,823,977 | 6,734,099 | 14,119,885 | 33,670,495 | 87,543,287 | 437,716,435 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -2,015 | -217,229 | -1,086,145 | -2,823,977 | -6,734,099 | -14,119,885 | -33,670,495 | -87,543,287 | -437,716,435 |
