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 101,515,765, 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 | 101,515,765 | |
| -1 | -101,515,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,515,765.
Example:
1 x 101,515,765 = 101,515,765
and
-1 x -101,515,765 = 101,515,765
Notice both answers equal 101,515,765
With that explanation out of the way, let's continue. Next, we take the number 101,515,765 and divide it by 2:
101,515,765 ÷ 2 = 50,757,882.5
If the quotient is a whole number, then 2 and 50,757,882.5 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 | 101,515,765 | |
| -1 | -101,515,765 |
Now, we try dividing 101,515,765 by 3:
101,515,765 ÷ 3 = 33,838,588.3333
If the quotient is a whole number, then 3 and 33,838,588.3333 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 | 101,515,765 | |
| -1 | -101,515,765 |
Let's try dividing by 4:
101,515,765 ÷ 4 = 25,378,941.25
If the quotient is a whole number, then 4 and 25,378,941.25 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 | 101,515,765 | |
| -1 | 101,515,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 169 | 247 | 845 | 1,235 | 3,211 | 6,323 | 16,055 | 31,615 | 82,199 | 120,137 | 410,995 | 600,685 | 1,068,587 | 1,561,781 | 5,342,935 | 7,808,905 | 20,303,153 | 101,515,765 |
| -1 | -5 | -13 | -19 | -65 | -95 | -169 | -247 | -845 | -1,235 | -3,211 | -6,323 | -16,055 | -31,615 | -82,199 | -120,137 | -410,995 | -600,685 | -1,068,587 | -1,561,781 | -5,342,935 | -7,808,905 | -20,303,153 | -101,515,765 |
