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 101,303,201, 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 | 101,303,201 | |
| -1 | -101,303,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,303,201.
Example:
1 x 101,303,201 = 101,303,201
and
-1 x -101,303,201 = 101,303,201
Notice both answers equal 101,303,201
With that explanation out of the way, let's continue. Next, we take the number 101,303,201 and divide it by 2:
101,303,201 ÷ 2 = 50,651,600.5
If the quotient is a whole number, then 2 and 50,651,600.5 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 | 101,303,201 | |
| -1 | -101,303,201 |
Now, we try dividing 101,303,201 by 3:
101,303,201 ÷ 3 = 33,767,733.6667
If the quotient is a whole number, then 3 and 33,767,733.6667 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 | 101,303,201 | |
| -1 | -101,303,201 |
Let's try dividing by 4:
101,303,201 ÷ 4 = 25,325,800.25
If the quotient is a whole number, then 4 and 25,325,800.25 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 | 101,303,201 | |
| -1 | 101,303,201 |
If you did it right, you will end up with this table:
| 1 | 23 | 79 | 127 | 439 | 1,817 | 2,921 | 10,033 | 10,097 | 34,681 | 55,753 | 230,759 | 797,663 | 1,282,319 | 4,404,487 | 101,303,201 |
| -1 | -23 | -79 | -127 | -439 | -1,817 | -2,921 | -10,033 | -10,097 | -34,681 | -55,753 | -230,759 | -797,663 | -1,282,319 | -4,404,487 | -101,303,201 |
