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 55,045,543, 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 | 55,045,543 | |
| -1 | -55,045,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,045,543.
Example:
1 x 55,045,543 = 55,045,543
and
-1 x -55,045,543 = 55,045,543
Notice both answers equal 55,045,543
With that explanation out of the way, let's continue. Next, we take the number 55,045,543 and divide it by 2:
55,045,543 ÷ 2 = 27,522,771.5
If the quotient is a whole number, then 2 and 27,522,771.5 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 | 55,045,543 | |
| -1 | -55,045,543 |
Now, we try dividing 55,045,543 by 3:
55,045,543 ÷ 3 = 18,348,514.3333
If the quotient is a whole number, then 3 and 18,348,514.3333 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 | 55,045,543 | |
| -1 | -55,045,543 |
Let's try dividing by 4:
55,045,543 ÷ 4 = 13,761,385.75
If the quotient is a whole number, then 4 and 13,761,385.75 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 | 55,045,543 | |
| -1 | 55,045,543 |
If you did it right, you will end up with this table:
| 1 | 7 | 179 | 197 | 223 | 1,253 | 1,379 | 1,561 | 35,263 | 39,917 | 43,931 | 246,841 | 279,419 | 307,517 | 7,863,649 | 55,045,543 |
| -1 | -7 | -179 | -197 | -223 | -1,253 | -1,379 | -1,561 | -35,263 | -39,917 | -43,931 | -246,841 | -279,419 | -307,517 | -7,863,649 | -55,045,543 |
