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 55,214,249, 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 | 55,214,249 | |
| -1 | -55,214,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,214,249.
Example:
1 x 55,214,249 = 55,214,249
and
-1 x -55,214,249 = 55,214,249
Notice both answers equal 55,214,249
With that explanation out of the way, let's continue. Next, we take the number 55,214,249 and divide it by 2:
55,214,249 ÷ 2 = 27,607,124.5
If the quotient is a whole number, then 2 and 27,607,124.5 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 | 55,214,249 | |
| -1 | -55,214,249 |
Now, we try dividing 55,214,249 by 3:
55,214,249 ÷ 3 = 18,404,749.6667
If the quotient is a whole number, then 3 and 18,404,749.6667 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 | 55,214,249 | |
| -1 | -55,214,249 |
Let's try dividing by 4:
55,214,249 ÷ 4 = 13,803,562.25
If the quotient is a whole number, then 4 and 13,803,562.25 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 | 55,214,249 | |
| -1 | 55,214,249 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 41 | 629 | 697 | 1,517 | 2,141 | 25,789 | 36,397 | 79,217 | 87,781 | 1,346,689 | 1,492,277 | 3,247,897 | 55,214,249 |
| -1 | -17 | -37 | -41 | -629 | -697 | -1,517 | -2,141 | -25,789 | -36,397 | -79,217 | -87,781 | -1,346,689 | -1,492,277 | -3,247,897 | -55,214,249 |
