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 204,152,543, 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 | 204,152,543 | |
| -1 | -204,152,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,152,543.
Example:
1 x 204,152,543 = 204,152,543
and
-1 x -204,152,543 = 204,152,543
Notice both answers equal 204,152,543
With that explanation out of the way, let's continue. Next, we take the number 204,152,543 and divide it by 2:
204,152,543 ÷ 2 = 102,076,271.5
If the quotient is a whole number, then 2 and 102,076,271.5 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 | 204,152,543 | |
| -1 | -204,152,543 |
Now, we try dividing 204,152,543 by 3:
204,152,543 ÷ 3 = 68,050,847.6667
If the quotient is a whole number, then 3 and 68,050,847.6667 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 | 204,152,543 | |
| -1 | -204,152,543 |
Let's try dividing by 4:
204,152,543 ÷ 4 = 51,038,135.75
If the quotient is a whole number, then 4 and 51,038,135.75 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 | 204,152,543 | |
| -1 | 204,152,543 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 179 | 427 | 1,253 | 2,671 | 10,919 | 18,697 | 76,433 | 162,931 | 478,109 | 1,140,517 | 3,346,763 | 29,164,649 | 204,152,543 |
| -1 | -7 | -61 | -179 | -427 | -1,253 | -2,671 | -10,919 | -18,697 | -76,433 | -162,931 | -478,109 | -1,140,517 | -3,346,763 | -29,164,649 | -204,152,543 |
