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 55,454,245, 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 | 55,454,245 | |
| -1 | -55,454,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,454,245.
Example:
1 x 55,454,245 = 55,454,245
and
-1 x -55,454,245 = 55,454,245
Notice both answers equal 55,454,245
With that explanation out of the way, let's continue. Next, we take the number 55,454,245 and divide it by 2:
55,454,245 ÷ 2 = 27,727,122.5
If the quotient is a whole number, then 2 and 27,727,122.5 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 | 55,454,245 | |
| -1 | -55,454,245 |
Now, we try dividing 55,454,245 by 3:
55,454,245 ÷ 3 = 18,484,748.3333
If the quotient is a whole number, then 3 and 18,484,748.3333 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 | 55,454,245 | |
| -1 | -55,454,245 |
Let's try dividing by 4:
55,454,245 ÷ 4 = 13,863,561.25
If the quotient is a whole number, then 4 and 13,863,561.25 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 | 55,454,245 | |
| -1 | 55,454,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 144,037 | 720,185 | 1,008,259 | 1,584,407 | 5,041,295 | 7,922,035 | 11,090,849 | 55,454,245 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -144,037 | -720,185 | -1,008,259 | -1,584,407 | -5,041,295 | -7,922,035 | -11,090,849 | -55,454,245 |
