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 60,848,249, 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 | 60,848,249 | |
| -1 | -60,848,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,848,249.
Example:
1 x 60,848,249 = 60,848,249
and
-1 x -60,848,249 = 60,848,249
Notice both answers equal 60,848,249
With that explanation out of the way, let's continue. Next, we take the number 60,848,249 and divide it by 2:
60,848,249 ÷ 2 = 30,424,124.5
If the quotient is a whole number, then 2 and 30,424,124.5 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 | 60,848,249 | |
| -1 | -60,848,249 |
Now, we try dividing 60,848,249 by 3:
60,848,249 ÷ 3 = 20,282,749.6667
If the quotient is a whole number, then 3 and 20,282,749.6667 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 | 60,848,249 | |
| -1 | -60,848,249 |
Let's try dividing by 4:
60,848,249 ÷ 4 = 15,212,062.25
If the quotient is a whole number, then 4 and 15,212,062.25 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 | 60,848,249 | |
| -1 | 60,848,249 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 79 | 539 | 553 | 869 | 1,429 | 3,871 | 6,083 | 10,003 | 15,719 | 42,581 | 70,021 | 110,033 | 112,891 | 770,231 | 790,237 | 1,241,801 | 5,531,659 | 8,692,607 | 60,848,249 |
| -1 | -7 | -11 | -49 | -77 | -79 | -539 | -553 | -869 | -1,429 | -3,871 | -6,083 | -10,003 | -15,719 | -42,581 | -70,021 | -110,033 | -112,891 | -770,231 | -790,237 | -1,241,801 | -5,531,659 | -8,692,607 | -60,848,249 |
