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 545,465,263, 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 | 545,465,263 | |
| -1 | -545,465,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 545,465,263.
Example:
1 x 545,465,263 = 545,465,263
and
-1 x -545,465,263 = 545,465,263
Notice both answers equal 545,465,263
With that explanation out of the way, let's continue. Next, we take the number 545,465,263 and divide it by 2:
545,465,263 ÷ 2 = 272,732,631.5
If the quotient is a whole number, then 2 and 272,732,631.5 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 | 545,465,263 | |
| -1 | -545,465,263 |
Now, we try dividing 545,465,263 by 3:
545,465,263 ÷ 3 = 181,821,754.3333
If the quotient is a whole number, then 3 and 181,821,754.3333 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 | 545,465,263 | |
| -1 | -545,465,263 |
Let's try dividing by 4:
545,465,263 ÷ 4 = 136,366,315.75
If the quotient is a whole number, then 4 and 136,366,315.75 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 | 545,465,263 | |
| -1 | 545,465,263 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 116,827 | 817,789 | 2,687,021 | 3,387,983 | 18,809,147 | 23,715,881 | 77,923,609 | 545,465,263 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -116,827 | -817,789 | -2,687,021 | -3,387,983 | -18,809,147 | -23,715,881 | -77,923,609 | -545,465,263 |
