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 54,245,765, 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 | 54,245,765 | |
| -1 | -54,245,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,245,765.
Example:
1 x 54,245,765 = 54,245,765
and
-1 x -54,245,765 = 54,245,765
Notice both answers equal 54,245,765
With that explanation out of the way, let's continue. Next, we take the number 54,245,765 and divide it by 2:
54,245,765 ÷ 2 = 27,122,882.5
If the quotient is a whole number, then 2 and 27,122,882.5 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 | 54,245,765 | |
| -1 | -54,245,765 |
Now, we try dividing 54,245,765 by 3:
54,245,765 ÷ 3 = 18,081,921.6667
If the quotient is a whole number, then 3 and 18,081,921.6667 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 | 54,245,765 | |
| -1 | -54,245,765 |
Let's try dividing by 4:
54,245,765 ÷ 4 = 13,561,441.25
If the quotient is a whole number, then 4 and 13,561,441.25 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 | 54,245,765 | |
| -1 | 54,245,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 29,243 | 146,215 | 204,701 | 1,023,505 | 1,549,879 | 7,749,395 | 10,849,153 | 54,245,765 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -29,243 | -146,215 | -204,701 | -1,023,505 | -1,549,879 | -7,749,395 | -10,849,153 | -54,245,765 |
