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 201,550,475, 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 | 201,550,475 | |
| -1 | -201,550,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,550,475.
Example:
1 x 201,550,475 = 201,550,475
and
-1 x -201,550,475 = 201,550,475
Notice both answers equal 201,550,475
With that explanation out of the way, let's continue. Next, we take the number 201,550,475 and divide it by 2:
201,550,475 ÷ 2 = 100,775,237.5
If the quotient is a whole number, then 2 and 100,775,237.5 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 | 201,550,475 | |
| -1 | -201,550,475 |
Now, we try dividing 201,550,475 by 3:
201,550,475 ÷ 3 = 67,183,491.6667
If the quotient is a whole number, then 3 and 67,183,491.6667 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 | 201,550,475 | |
| -1 | -201,550,475 |
Let's try dividing by 4:
201,550,475 ÷ 4 = 50,387,618.75
If the quotient is a whole number, then 4 and 50,387,618.75 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 | 201,550,475 | |
| -1 | 201,550,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 164,531 | 822,655 | 1,151,717 | 4,113,275 | 5,758,585 | 8,062,019 | 28,792,925 | 40,310,095 | 201,550,475 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -164,531 | -822,655 | -1,151,717 | -4,113,275 | -5,758,585 | -8,062,019 | -28,792,925 | -40,310,095 | -201,550,475 |
