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 105,116,423, 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 | 105,116,423 | |
| -1 | -105,116,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,116,423.
Example:
1 x 105,116,423 = 105,116,423
and
-1 x -105,116,423 = 105,116,423
Notice both answers equal 105,116,423
With that explanation out of the way, let's continue. Next, we take the number 105,116,423 and divide it by 2:
105,116,423 ÷ 2 = 52,558,211.5
If the quotient is a whole number, then 2 and 52,558,211.5 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 | 105,116,423 | |
| -1 | -105,116,423 |
Now, we try dividing 105,116,423 by 3:
105,116,423 ÷ 3 = 35,038,807.6667
If the quotient is a whole number, then 3 and 35,038,807.6667 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 | 105,116,423 | |
| -1 | -105,116,423 |
Let's try dividing by 4:
105,116,423 ÷ 4 = 26,279,105.75
If the quotient is a whole number, then 4 and 26,279,105.75 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 | 105,116,423 | |
| -1 | 105,116,423 |
If you did it right, you will end up with this table:
| 1 | 17 | 71 | 73 | 1,193 | 1,207 | 1,241 | 5,183 | 20,281 | 84,703 | 87,089 | 88,111 | 1,439,951 | 1,480,513 | 6,183,319 | 105,116,423 |
| -1 | -17 | -71 | -73 | -1,193 | -1,207 | -1,241 | -5,183 | -20,281 | -84,703 | -87,089 | -88,111 | -1,439,951 | -1,480,513 | -6,183,319 | -105,116,423 |
