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 206,334,565, 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 | 206,334,565 | |
| -1 | -206,334,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,334,565.
Example:
1 x 206,334,565 = 206,334,565
and
-1 x -206,334,565 = 206,334,565
Notice both answers equal 206,334,565
With that explanation out of the way, let's continue. Next, we take the number 206,334,565 and divide it by 2:
206,334,565 ÷ 2 = 103,167,282.5
If the quotient is a whole number, then 2 and 103,167,282.5 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 | 206,334,565 | |
| -1 | -206,334,565 |
Now, we try dividing 206,334,565 by 3:
206,334,565 ÷ 3 = 68,778,188.3333
If the quotient is a whole number, then 3 and 68,778,188.3333 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 | 206,334,565 | |
| -1 | -206,334,565 |
Let's try dividing by 4:
206,334,565 ÷ 4 = 51,583,641.25
If the quotient is a whole number, then 4 and 51,583,641.25 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 | 206,334,565 | |
| -1 | 206,334,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 265 | 1,537 | 7,685 | 26,849 | 134,245 | 778,621 | 1,422,997 | 3,893,105 | 7,114,985 | 41,266,913 | 206,334,565 |
| -1 | -5 | -29 | -53 | -145 | -265 | -1,537 | -7,685 | -26,849 | -134,245 | -778,621 | -1,422,997 | -3,893,105 | -7,114,985 | -41,266,913 | -206,334,565 |
