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 202,150,565, 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 | 202,150,565 | |
| -1 | -202,150,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,150,565.
Example:
1 x 202,150,565 = 202,150,565
and
-1 x -202,150,565 = 202,150,565
Notice both answers equal 202,150,565
With that explanation out of the way, let's continue. Next, we take the number 202,150,565 and divide it by 2:
202,150,565 ÷ 2 = 101,075,282.5
If the quotient is a whole number, then 2 and 101,075,282.5 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 | 202,150,565 | |
| -1 | -202,150,565 |
Now, we try dividing 202,150,565 by 3:
202,150,565 ÷ 3 = 67,383,521.6667
If the quotient is a whole number, then 3 and 67,383,521.6667 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 | 202,150,565 | |
| -1 | -202,150,565 |
Let's try dividing by 4:
202,150,565 ÷ 4 = 50,537,641.25
If the quotient is a whole number, then 4 and 50,537,641.25 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 | 202,150,565 | |
| -1 | 202,150,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 197 | 985 | 4,531 | 8,923 | 22,655 | 44,615 | 205,229 | 1,026,145 | 1,757,831 | 8,789,155 | 40,430,113 | 202,150,565 |
| -1 | -5 | -23 | -115 | -197 | -985 | -4,531 | -8,923 | -22,655 | -44,615 | -205,229 | -1,026,145 | -1,757,831 | -8,789,155 | -40,430,113 | -202,150,565 |
