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 219,224,423, 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 | 219,224,423 | |
| -1 | -219,224,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 219,224,423.
Example:
1 x 219,224,423 = 219,224,423
and
-1 x -219,224,423 = 219,224,423
Notice both answers equal 219,224,423
With that explanation out of the way, let's continue. Next, we take the number 219,224,423 and divide it by 2:
219,224,423 ÷ 2 = 109,612,211.5
If the quotient is a whole number, then 2 and 109,612,211.5 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 | 219,224,423 | |
| -1 | -219,224,423 |
Now, we try dividing 219,224,423 by 3:
219,224,423 ÷ 3 = 73,074,807.6667
If the quotient is a whole number, then 3 and 73,074,807.6667 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 | 219,224,423 | |
| -1 | -219,224,423 |
Let's try dividing by 4:
219,224,423 ÷ 4 = 54,806,105.75
If the quotient is a whole number, then 4 and 54,806,105.75 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 | 219,224,423 | |
| -1 | 219,224,423 |
If you did it right, you will end up with this table:
| 1 | 11 | 61 | 239 | 671 | 1,367 | 2,629 | 14,579 | 15,037 | 83,387 | 160,369 | 326,713 | 917,257 | 3,593,843 | 19,929,493 | 219,224,423 |
| -1 | -11 | -61 | -239 | -671 | -1,367 | -2,629 | -14,579 | -15,037 | -83,387 | -160,369 | -326,713 | -917,257 | -3,593,843 | -19,929,493 | -219,224,423 |
