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 54,628,249, 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 | 54,628,249 | |
| -1 | -54,628,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,628,249.
Example:
1 x 54,628,249 = 54,628,249
and
-1 x -54,628,249 = 54,628,249
Notice both answers equal 54,628,249
With that explanation out of the way, let's continue. Next, we take the number 54,628,249 and divide it by 2:
54,628,249 ÷ 2 = 27,314,124.5
If the quotient is a whole number, then 2 and 27,314,124.5 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 | 54,628,249 | |
| -1 | -54,628,249 |
Now, we try dividing 54,628,249 by 3:
54,628,249 ÷ 3 = 18,209,416.3333
If the quotient is a whole number, then 3 and 18,209,416.3333 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 | 54,628,249 | |
| -1 | -54,628,249 |
Let's try dividing by 4:
54,628,249 ÷ 4 = 13,657,062.25
If the quotient is a whole number, then 4 and 13,657,062.25 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 | 54,628,249 | |
| -1 | 54,628,249 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 67 | 247 | 871 | 1,273 | 3,301 | 16,549 | 42,913 | 62,719 | 221,167 | 815,347 | 2,875,171 | 4,202,173 | 54,628,249 |
| -1 | -13 | -19 | -67 | -247 | -871 | -1,273 | -3,301 | -16,549 | -42,913 | -62,719 | -221,167 | -815,347 | -2,875,171 | -4,202,173 | -54,628,249 |
