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 101,817,175, 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 | 101,817,175 | |
| -1 | -101,817,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,817,175.
Example:
1 x 101,817,175 = 101,817,175
and
-1 x -101,817,175 = 101,817,175
Notice both answers equal 101,817,175
With that explanation out of the way, let's continue. Next, we take the number 101,817,175 and divide it by 2:
101,817,175 ÷ 2 = 50,908,587.5
If the quotient is a whole number, then 2 and 50,908,587.5 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 | 101,817,175 | |
| -1 | -101,817,175 |
Now, we try dividing 101,817,175 by 3:
101,817,175 ÷ 3 = 33,939,058.3333
If the quotient is a whole number, then 3 and 33,939,058.3333 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 | 101,817,175 | |
| -1 | -101,817,175 |
Let's try dividing by 4:
101,817,175 ÷ 4 = 25,454,293.75
If the quotient is a whole number, then 4 and 25,454,293.75 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 | 101,817,175 | |
| -1 | 101,817,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 79 | 155 | 395 | 775 | 1,663 | 1,975 | 2,449 | 8,315 | 12,245 | 41,575 | 51,553 | 61,225 | 131,377 | 257,765 | 656,885 | 1,288,825 | 3,284,425 | 4,072,687 | 20,363,435 | 101,817,175 |
| -1 | -5 | -25 | -31 | -79 | -155 | -395 | -775 | -1,663 | -1,975 | -2,449 | -8,315 | -12,245 | -41,575 | -51,553 | -61,225 | -131,377 | -257,765 | -656,885 | -1,288,825 | -3,284,425 | -4,072,687 | -20,363,435 | -101,817,175 |
