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 100,023,343, 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 | 100,023,343 | |
| -1 | -100,023,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,023,343.
Example:
1 x 100,023,343 = 100,023,343
and
-1 x -100,023,343 = 100,023,343
Notice both answers equal 100,023,343
With that explanation out of the way, let's continue. Next, we take the number 100,023,343 and divide it by 2:
100,023,343 ÷ 2 = 50,011,671.5
If the quotient is a whole number, then 2 and 50,011,671.5 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 | 100,023,343 | |
| -1 | -100,023,343 |
Now, we try dividing 100,023,343 by 3:
100,023,343 ÷ 3 = 33,341,114.3333
If the quotient is a whole number, then 3 and 33,341,114.3333 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 | 100,023,343 | |
| -1 | -100,023,343 |
Let's try dividing by 4:
100,023,343 ÷ 4 = 25,005,835.75
If the quotient is a whole number, then 4 and 25,005,835.75 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 | 100,023,343 | |
| -1 | 100,023,343 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 479 | 1,297 | 3,353 | 9,079 | 11,017 | 29,831 | 77,119 | 208,817 | 621,263 | 4,348,841 | 14,289,049 | 100,023,343 |
| -1 | -7 | -23 | -161 | -479 | -1,297 | -3,353 | -9,079 | -11,017 | -29,831 | -77,119 | -208,817 | -621,263 | -4,348,841 | -14,289,049 | -100,023,343 |
