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 545,853,535, 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 | 545,853,535 | |
| -1 | -545,853,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 545,853,535.
Example:
1 x 545,853,535 = 545,853,535
and
-1 x -545,853,535 = 545,853,535
Notice both answers equal 545,853,535
With that explanation out of the way, let's continue. Next, we take the number 545,853,535 and divide it by 2:
545,853,535 ÷ 2 = 272,926,767.5
If the quotient is a whole number, then 2 and 272,926,767.5 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 | 545,853,535 | |
| -1 | -545,853,535 |
Now, we try dividing 545,853,535 by 3:
545,853,535 ÷ 3 = 181,951,178.3333
If the quotient is a whole number, then 3 and 181,951,178.3333 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 | 545,853,535 | |
| -1 | -545,853,535 |
Let's try dividing by 4:
545,853,535 ÷ 4 = 136,463,383.75
If the quotient is a whole number, then 4 and 136,463,383.75 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 | 545,853,535 | |
| -1 | 545,853,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 593 | 2,965 | 3,917 | 19,585 | 27,871 | 139,355 | 184,099 | 920,495 | 2,322,781 | 11,613,905 | 109,170,707 | 545,853,535 |
| -1 | -5 | -47 | -235 | -593 | -2,965 | -3,917 | -19,585 | -27,871 | -139,355 | -184,099 | -920,495 | -2,322,781 | -11,613,905 | -109,170,707 | -545,853,535 |
