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 201,401,465, 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 | 201,401,465 | |
| -1 | -201,401,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,401,465.
Example:
1 x 201,401,465 = 201,401,465
and
-1 x -201,401,465 = 201,401,465
Notice both answers equal 201,401,465
With that explanation out of the way, let's continue. Next, we take the number 201,401,465 and divide it by 2:
201,401,465 ÷ 2 = 100,700,732.5
If the quotient is a whole number, then 2 and 100,700,732.5 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 | 201,401,465 | |
| -1 | -201,401,465 |
Now, we try dividing 201,401,465 by 3:
201,401,465 ÷ 3 = 67,133,821.6667
If the quotient is a whole number, then 3 and 67,133,821.6667 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 | 201,401,465 | |
| -1 | -201,401,465 |
Let's try dividing by 4:
201,401,465 ÷ 4 = 50,350,366.25
If the quotient is a whole number, then 4 and 50,350,366.25 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 | 201,401,465 | |
| -1 | 201,401,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 3,655 | 55,103 | 275,515 | 936,751 | 2,369,429 | 4,683,755 | 11,847,145 | 40,280,293 | 201,401,465 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -3,655 | -55,103 | -275,515 | -936,751 | -2,369,429 | -4,683,755 | -11,847,145 | -40,280,293 | -201,401,465 |
