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 437,225,663, 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 | 437,225,663 | |
| -1 | -437,225,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 437,225,663.
Example:
1 x 437,225,663 = 437,225,663
and
-1 x -437,225,663 = 437,225,663
Notice both answers equal 437,225,663
With that explanation out of the way, let's continue. Next, we take the number 437,225,663 and divide it by 2:
437,225,663 ÷ 2 = 218,612,831.5
If the quotient is a whole number, then 2 and 218,612,831.5 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 | 437,225,663 | |
| -1 | -437,225,663 |
Now, we try dividing 437,225,663 by 3:
437,225,663 ÷ 3 = 145,741,887.6667
If the quotient is a whole number, then 3 and 145,741,887.6667 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 | 437,225,663 | |
| -1 | -437,225,663 |
Let's try dividing by 4:
437,225,663 ÷ 4 = 109,306,415.75
If the quotient is a whole number, then 4 and 109,306,415.75 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 | 437,225,663 | |
| -1 | 437,225,663 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 29 | 133 | 203 | 551 | 3,857 | 113,359 | 793,513 | 2,153,821 | 3,287,411 | 15,076,747 | 23,011,877 | 62,460,809 | 437,225,663 |
| -1 | -7 | -19 | -29 | -133 | -203 | -551 | -3,857 | -113,359 | -793,513 | -2,153,821 | -3,287,411 | -15,076,747 | -23,011,877 | -62,460,809 | -437,225,663 |
