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 201,715,615, 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 | 201,715,615 | |
| -1 | -201,715,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,715,615.
Example:
1 x 201,715,615 = 201,715,615
and
-1 x -201,715,615 = 201,715,615
Notice both answers equal 201,715,615
With that explanation out of the way, let's continue. Next, we take the number 201,715,615 and divide it by 2:
201,715,615 ÷ 2 = 100,857,807.5
If the quotient is a whole number, then 2 and 100,857,807.5 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 | 201,715,615 | |
| -1 | -201,715,615 |
Now, we try dividing 201,715,615 by 3:
201,715,615 ÷ 3 = 67,238,538.3333
If the quotient is a whole number, then 3 and 67,238,538.3333 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 | 201,715,615 | |
| -1 | -201,715,615 |
Let's try dividing by 4:
201,715,615 ÷ 4 = 50,428,903.75
If the quotient is a whole number, then 4 and 50,428,903.75 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 | 201,715,615 | |
| -1 | 201,715,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 71 | 151 | 265 | 355 | 755 | 3,763 | 5,041 | 8,003 | 10,721 | 18,815 | 25,205 | 40,015 | 53,605 | 267,173 | 568,213 | 761,191 | 1,335,865 | 2,841,065 | 3,805,955 | 40,343,123 | 201,715,615 |
| -1 | -5 | -53 | -71 | -151 | -265 | -355 | -755 | -3,763 | -5,041 | -8,003 | -10,721 | -18,815 | -25,205 | -40,015 | -53,605 | -267,173 | -568,213 | -761,191 | -1,335,865 | -2,841,065 | -3,805,955 | -40,343,123 | -201,715,615 |
