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 654,066,179, 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 | 654,066,179 | |
| -1 | -654,066,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 654,066,179.
Example:
1 x 654,066,179 = 654,066,179
and
-1 x -654,066,179 = 654,066,179
Notice both answers equal 654,066,179
With that explanation out of the way, let's continue. Next, we take the number 654,066,179 and divide it by 2:
654,066,179 ÷ 2 = 327,033,089.5
If the quotient is a whole number, then 2 and 327,033,089.5 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 | 654,066,179 | |
| -1 | -654,066,179 |
Now, we try dividing 654,066,179 by 3:
654,066,179 ÷ 3 = 218,022,059.6667
If the quotient is a whole number, then 3 and 218,022,059.6667 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 | 654,066,179 | |
| -1 | -654,066,179 |
Let's try dividing by 4:
654,066,179 ÷ 4 = 163,516,544.75
If the quotient is a whole number, then 4 and 163,516,544.75 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 | 654,066,179 | |
| -1 | 654,066,179 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 179 | 403 | 2,327 | 5,549 | 9,067 | 72,137 | 117,871 | 281,077 | 1,622,993 | 3,654,001 | 21,098,909 | 50,312,783 | 654,066,179 |
| -1 | -13 | -31 | -179 | -403 | -2,327 | -5,549 | -9,067 | -72,137 | -117,871 | -281,077 | -1,622,993 | -3,654,001 | -21,098,909 | -50,312,783 | -654,066,179 |
