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 100,407,673, 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 | 100,407,673 | |
| -1 | -100,407,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,407,673.
Example:
1 x 100,407,673 = 100,407,673
and
-1 x -100,407,673 = 100,407,673
Notice both answers equal 100,407,673
With that explanation out of the way, let's continue. Next, we take the number 100,407,673 and divide it by 2:
100,407,673 ÷ 2 = 50,203,836.5
If the quotient is a whole number, then 2 and 50,203,836.5 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 | 100,407,673 | |
| -1 | -100,407,673 |
Now, we try dividing 100,407,673 by 3:
100,407,673 ÷ 3 = 33,469,224.3333
If the quotient is a whole number, then 3 and 33,469,224.3333 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 | 100,407,673 | |
| -1 | -100,407,673 |
Let's try dividing by 4:
100,407,673 ÷ 4 = 25,101,918.25
If the quotient is a whole number, then 4 and 25,101,918.25 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 | 100,407,673 | |
| -1 | 100,407,673 |
If you did it right, you will end up with this table:
| 1 | 23 | 83 | 149 | 353 | 1,909 | 3,427 | 8,119 | 12,367 | 29,299 | 52,597 | 284,441 | 673,877 | 1,209,731 | 4,365,551 | 100,407,673 |
| -1 | -23 | -83 | -149 | -353 | -1,909 | -3,427 | -8,119 | -12,367 | -29,299 | -52,597 | -284,441 | -673,877 | -1,209,731 | -4,365,551 | -100,407,673 |
