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 551,566,601, 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 | 551,566,601 | |
| -1 | -551,566,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 551,566,601.
Example:
1 x 551,566,601 = 551,566,601
and
-1 x -551,566,601 = 551,566,601
Notice both answers equal 551,566,601
With that explanation out of the way, let's continue. Next, we take the number 551,566,601 and divide it by 2:
551,566,601 ÷ 2 = 275,783,300.5
If the quotient is a whole number, then 2 and 275,783,300.5 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 | 551,566,601 | |
| -1 | -551,566,601 |
Now, we try dividing 551,566,601 by 3:
551,566,601 ÷ 3 = 183,855,533.6667
If the quotient is a whole number, then 3 and 183,855,533.6667 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 | 551,566,601 | |
| -1 | -551,566,601 |
Let's try dividing by 4:
551,566,601 ÷ 4 = 137,891,650.25
If the quotient is a whole number, then 4 and 137,891,650.25 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 | 551,566,601 | |
| -1 | 551,566,601 |
If you did it right, you will end up with this table:
| 1 | 31 | 53 | 389 | 863 | 1,643 | 12,059 | 20,617 | 26,753 | 45,739 | 335,707 | 639,127 | 1,417,909 | 10,406,917 | 17,792,471 | 551,566,601 |
| -1 | -31 | -53 | -389 | -863 | -1,643 | -12,059 | -20,617 | -26,753 | -45,739 | -335,707 | -639,127 | -1,417,909 | -10,406,917 | -17,792,471 | -551,566,601 |
