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 101,002,195, 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 | 101,002,195 | |
| -1 | -101,002,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,002,195.
Example:
1 x 101,002,195 = 101,002,195
and
-1 x -101,002,195 = 101,002,195
Notice both answers equal 101,002,195
With that explanation out of the way, let's continue. Next, we take the number 101,002,195 and divide it by 2:
101,002,195 ÷ 2 = 50,501,097.5
If the quotient is a whole number, then 2 and 50,501,097.5 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 | 101,002,195 | |
| -1 | -101,002,195 |
Now, we try dividing 101,002,195 by 3:
101,002,195 ÷ 3 = 33,667,398.3333
If the quotient is a whole number, then 3 and 33,667,398.3333 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 | 101,002,195 | |
| -1 | -101,002,195 |
Let's try dividing by 4:
101,002,195 ÷ 4 = 25,250,548.75
If the quotient is a whole number, then 4 and 25,250,548.75 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 | 101,002,195 | |
| -1 | 101,002,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 151,883 | 759,415 | 1,063,181 | 2,885,777 | 5,315,905 | 14,428,885 | 20,200,439 | 101,002,195 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -151,883 | -759,415 | -1,063,181 | -2,885,777 | -5,315,905 | -14,428,885 | -20,200,439 | -101,002,195 |
