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 55,078,247, 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 | 55,078,247 | |
| -1 | -55,078,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,078,247.
Example:
1 x 55,078,247 = 55,078,247
and
-1 x -55,078,247 = 55,078,247
Notice both answers equal 55,078,247
With that explanation out of the way, let's continue. Next, we take the number 55,078,247 and divide it by 2:
55,078,247 ÷ 2 = 27,539,123.5
If the quotient is a whole number, then 2 and 27,539,123.5 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 | 55,078,247 | |
| -1 | -55,078,247 |
Now, we try dividing 55,078,247 by 3:
55,078,247 ÷ 3 = 18,359,415.6667
If the quotient is a whole number, then 3 and 18,359,415.6667 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 | 55,078,247 | |
| -1 | -55,078,247 |
Let's try dividing by 4:
55,078,247 ÷ 4 = 13,769,561.75
If the quotient is a whole number, then 4 and 13,769,561.75 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 | 55,078,247 | |
| -1 | 55,078,247 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 137 | 553 | 727 | 959 | 5,089 | 10,823 | 57,433 | 75,761 | 99,599 | 402,031 | 697,193 | 7,868,321 | 55,078,247 |
| -1 | -7 | -79 | -137 | -553 | -727 | -959 | -5,089 | -10,823 | -57,433 | -75,761 | -99,599 | -402,031 | -697,193 | -7,868,321 | -55,078,247 |
