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 556,340,767, 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 | 556,340,767 | |
| -1 | -556,340,767 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 556,340,767.
Example:
1 x 556,340,767 = 556,340,767
and
-1 x -556,340,767 = 556,340,767
Notice both answers equal 556,340,767
With that explanation out of the way, let's continue. Next, we take the number 556,340,767 and divide it by 2:
556,340,767 ÷ 2 = 278,170,383.5
If the quotient is a whole number, then 2 and 278,170,383.5 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 | 556,340,767 | |
| -1 | -556,340,767 |
Now, we try dividing 556,340,767 by 3:
556,340,767 ÷ 3 = 185,446,922.3333
If the quotient is a whole number, then 3 and 185,446,922.3333 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 | 556,340,767 | |
| -1 | -556,340,767 |
Let's try dividing by 4:
556,340,767 ÷ 4 = 139,085,191.75
If the quotient is a whole number, then 4 and 139,085,191.75 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 | 556,340,767 | |
| -1 | 556,340,767 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 41 | 437 | 779 | 943 | 17,917 | 31,051 | 589,969 | 714,173 | 1,273,091 | 13,569,287 | 24,188,729 | 29,281,093 | 556,340,767 |
| -1 | -19 | -23 | -41 | -437 | -779 | -943 | -17,917 | -31,051 | -589,969 | -714,173 | -1,273,091 | -13,569,287 | -24,188,729 | -29,281,093 | -556,340,767 |
