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 553,113,247, 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 | 553,113,247 | |
| -1 | -553,113,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,113,247.
Example:
1 x 553,113,247 = 553,113,247
and
-1 x -553,113,247 = 553,113,247
Notice both answers equal 553,113,247
With that explanation out of the way, let's continue. Next, we take the number 553,113,247 and divide it by 2:
553,113,247 ÷ 2 = 276,556,623.5
If the quotient is a whole number, then 2 and 276,556,623.5 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 | 553,113,247 | |
| -1 | -553,113,247 |
Now, we try dividing 553,113,247 by 3:
553,113,247 ÷ 3 = 184,371,082.3333
If the quotient is a whole number, then 3 and 184,371,082.3333 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 | 553,113,247 | |
| -1 | -553,113,247 |
Let's try dividing by 4:
553,113,247 ÷ 4 = 138,278,311.75
If the quotient is a whole number, then 4 and 138,278,311.75 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 | 553,113,247 | |
| -1 | 553,113,247 |
If you did it right, you will end up with this table:
| 1 | 41 | 53 | 331 | 769 | 2,173 | 13,571 | 17,543 | 31,529 | 40,757 | 254,539 | 719,263 | 1,671,037 | 10,436,099 | 13,490,567 | 553,113,247 |
| -1 | -41 | -53 | -331 | -769 | -2,173 | -13,571 | -17,543 | -31,529 | -40,757 | -254,539 | -719,263 | -1,671,037 | -10,436,099 | -13,490,567 | -553,113,247 |
