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 100,528,195, 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 | 100,528,195 | |
| -1 | -100,528,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,528,195.
Example:
1 x 100,528,195 = 100,528,195
and
-1 x -100,528,195 = 100,528,195
Notice both answers equal 100,528,195
With that explanation out of the way, let's continue. Next, we take the number 100,528,195 and divide it by 2:
100,528,195 ÷ 2 = 50,264,097.5
If the quotient is a whole number, then 2 and 50,264,097.5 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 | 100,528,195 | |
| -1 | -100,528,195 |
Now, we try dividing 100,528,195 by 3:
100,528,195 ÷ 3 = 33,509,398.3333
If the quotient is a whole number, then 3 and 33,509,398.3333 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 | 100,528,195 | |
| -1 | -100,528,195 |
Let's try dividing by 4:
100,528,195 ÷ 4 = 25,132,048.75
If the quotient is a whole number, then 4 and 25,132,048.75 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 | 100,528,195 | |
| -1 | 100,528,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 43 | 155 | 215 | 1,333 | 6,665 | 15,083 | 75,415 | 467,573 | 648,569 | 2,337,865 | 3,242,845 | 20,105,639 | 100,528,195 |
| -1 | -5 | -31 | -43 | -155 | -215 | -1,333 | -6,665 | -15,083 | -75,415 | -467,573 | -648,569 | -2,337,865 | -3,242,845 | -20,105,639 | -100,528,195 |
