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 200,153,545, 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 | 200,153,545 | |
| -1 | -200,153,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,153,545.
Example:
1 x 200,153,545 = 200,153,545
and
-1 x -200,153,545 = 200,153,545
Notice both answers equal 200,153,545
With that explanation out of the way, let's continue. Next, we take the number 200,153,545 and divide it by 2:
200,153,545 ÷ 2 = 100,076,772.5
If the quotient is a whole number, then 2 and 100,076,772.5 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 | 200,153,545 | |
| -1 | -200,153,545 |
Now, we try dividing 200,153,545 by 3:
200,153,545 ÷ 3 = 66,717,848.3333
If the quotient is a whole number, then 3 and 66,717,848.3333 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 | 200,153,545 | |
| -1 | -200,153,545 |
Let's try dividing by 4:
200,153,545 ÷ 4 = 50,038,386.25
If the quotient is a whole number, then 4 and 50,038,386.25 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 | 200,153,545 | |
| -1 | 200,153,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 193 | 211 | 965 | 983 | 1,055 | 4,915 | 40,723 | 189,719 | 203,615 | 207,413 | 948,595 | 1,037,065 | 40,030,709 | 200,153,545 |
| -1 | -5 | -193 | -211 | -965 | -983 | -1,055 | -4,915 | -40,723 | -189,719 | -203,615 | -207,413 | -948,595 | -1,037,065 | -40,030,709 | -200,153,545 |
