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 563,143,867, 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 | 563,143,867 | |
| -1 | -563,143,867 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 563,143,867.
Example:
1 x 563,143,867 = 563,143,867
and
-1 x -563,143,867 = 563,143,867
Notice both answers equal 563,143,867
With that explanation out of the way, let's continue. Next, we take the number 563,143,867 and divide it by 2:
563,143,867 ÷ 2 = 281,571,933.5
If the quotient is a whole number, then 2 and 281,571,933.5 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 | 563,143,867 | |
| -1 | -563,143,867 |
Now, we try dividing 563,143,867 by 3:
563,143,867 ÷ 3 = 187,714,622.3333
If the quotient is a whole number, then 3 and 187,714,622.3333 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 | 563,143,867 | |
| -1 | -563,143,867 |
Let's try dividing by 4:
563,143,867 ÷ 4 = 140,785,966.75
If the quotient is a whole number, then 4 and 140,785,966.75 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 | 563,143,867 | |
| -1 | 563,143,867 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 43 | 143 | 473 | 559 | 6,149 | 91,583 | 1,007,413 | 1,190,579 | 3,938,069 | 13,096,369 | 43,318,759 | 51,194,897 | 563,143,867 |
| -1 | -11 | -13 | -43 | -143 | -473 | -559 | -6,149 | -91,583 | -1,007,413 | -1,190,579 | -3,938,069 | -13,096,369 | -43,318,759 | -51,194,897 | -563,143,867 |
