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 513,683,423, 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 | 513,683,423 | |
| -1 | -513,683,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 513,683,423.
Example:
1 x 513,683,423 = 513,683,423
and
-1 x -513,683,423 = 513,683,423
Notice both answers equal 513,683,423
With that explanation out of the way, let's continue. Next, we take the number 513,683,423 and divide it by 2:
513,683,423 ÷ 2 = 256,841,711.5
If the quotient is a whole number, then 2 and 256,841,711.5 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 | 513,683,423 | |
| -1 | -513,683,423 |
Now, we try dividing 513,683,423 by 3:
513,683,423 ÷ 3 = 171,227,807.6667
If the quotient is a whole number, then 3 and 171,227,807.6667 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 | 513,683,423 | |
| -1 | -513,683,423 |
Let's try dividing by 4:
513,683,423 ÷ 4 = 128,420,855.75
If the quotient is a whole number, then 4 and 128,420,855.75 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 | 513,683,423 | |
| -1 | 513,683,423 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 113 | 341 | 1,243 | 3,503 | 13,331 | 38,533 | 146,641 | 413,261 | 1,506,403 | 4,545,871 | 16,570,433 | 46,698,493 | 513,683,423 |
| -1 | -11 | -31 | -113 | -341 | -1,243 | -3,503 | -13,331 | -38,533 | -146,641 | -413,261 | -1,506,403 | -4,545,871 | -16,570,433 | -46,698,493 | -513,683,423 |
