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 545,334,655, 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 | 545,334,655 | |
| -1 | -545,334,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 545,334,655.
Example:
1 x 545,334,655 = 545,334,655
and
-1 x -545,334,655 = 545,334,655
Notice both answers equal 545,334,655
With that explanation out of the way, let's continue. Next, we take the number 545,334,655 and divide it by 2:
545,334,655 ÷ 2 = 272,667,327.5
If the quotient is a whole number, then 2 and 272,667,327.5 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 | 545,334,655 | |
| -1 | -545,334,655 |
Now, we try dividing 545,334,655 by 3:
545,334,655 ÷ 3 = 181,778,218.3333
If the quotient is a whole number, then 3 and 181,778,218.3333 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 | 545,334,655 | |
| -1 | -545,334,655 |
Let's try dividing by 4:
545,334,655 ÷ 4 = 136,333,663.75
If the quotient is a whole number, then 4 and 136,333,663.75 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 | 545,334,655 | |
| -1 | 545,334,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 271 | 1,355 | 8,563 | 12,737 | 42,815 | 63,685 | 402,461 | 2,012,305 | 2,320,573 | 11,602,865 | 109,066,931 | 545,334,655 |
| -1 | -5 | -47 | -235 | -271 | -1,355 | -8,563 | -12,737 | -42,815 | -63,685 | -402,461 | -2,012,305 | -2,320,573 | -11,602,865 | -109,066,931 | -545,334,655 |
