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 536,455,865, 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 | 536,455,865 | |
| -1 | -536,455,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 536,455,865.
Example:
1 x 536,455,865 = 536,455,865
and
-1 x -536,455,865 = 536,455,865
Notice both answers equal 536,455,865
With that explanation out of the way, let's continue. Next, we take the number 536,455,865 and divide it by 2:
536,455,865 ÷ 2 = 268,227,932.5
If the quotient is a whole number, then 2 and 268,227,932.5 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 | 536,455,865 | |
| -1 | -536,455,865 |
Now, we try dividing 536,455,865 by 3:
536,455,865 ÷ 3 = 178,818,621.6667
If the quotient is a whole number, then 3 and 178,818,621.6667 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 | 536,455,865 | |
| -1 | -536,455,865 |
Let's try dividing by 4:
536,455,865 ÷ 4 = 134,113,966.25
If the quotient is a whole number, then 4 and 134,113,966.25 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 | 536,455,865 | |
| -1 | 536,455,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 353 | 1,765 | 3,883 | 19,415 | 27,631 | 138,155 | 303,941 | 1,519,705 | 9,753,743 | 48,768,715 | 107,291,173 | 536,455,865 |
| -1 | -5 | -11 | -55 | -353 | -1,765 | -3,883 | -19,415 | -27,631 | -138,155 | -303,941 | -1,519,705 | -9,753,743 | -48,768,715 | -107,291,173 | -536,455,865 |
