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 120,230,201, 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 | 120,230,201 | |
| -1 | -120,230,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,230,201.
Example:
1 x 120,230,201 = 120,230,201
and
-1 x -120,230,201 = 120,230,201
Notice both answers equal 120,230,201
With that explanation out of the way, let's continue. Next, we take the number 120,230,201 and divide it by 2:
120,230,201 ÷ 2 = 60,115,100.5
If the quotient is a whole number, then 2 and 60,115,100.5 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 | 120,230,201 | |
| -1 | -120,230,201 |
Now, we try dividing 120,230,201 by 3:
120,230,201 ÷ 3 = 40,076,733.6667
If the quotient is a whole number, then 3 and 40,076,733.6667 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 | 120,230,201 | |
| -1 | -120,230,201 |
Let's try dividing by 4:
120,230,201 ÷ 4 = 30,057,550.25
If the quotient is a whole number, then 4 and 30,057,550.25 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 | 120,230,201 | |
| -1 | 120,230,201 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 91 | 203 | 377 | 841 | 1,571 | 2,639 | 5,887 | 10,933 | 10,997 | 20,423 | 45,559 | 76,531 | 142,961 | 318,913 | 592,267 | 1,321,211 | 4,145,869 | 9,248,477 | 17,175,743 | 120,230,201 |
| -1 | -7 | -13 | -29 | -91 | -203 | -377 | -841 | -1,571 | -2,639 | -5,887 | -10,933 | -10,997 | -20,423 | -45,559 | -76,531 | -142,961 | -318,913 | -592,267 | -1,321,211 | -4,145,869 | -9,248,477 | -17,175,743 | -120,230,201 |
