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 54,324,745, 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 | 54,324,745 | |
| -1 | -54,324,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,324,745.
Example:
1 x 54,324,745 = 54,324,745
and
-1 x -54,324,745 = 54,324,745
Notice both answers equal 54,324,745
With that explanation out of the way, let's continue. Next, we take the number 54,324,745 and divide it by 2:
54,324,745 ÷ 2 = 27,162,372.5
If the quotient is a whole number, then 2 and 27,162,372.5 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 | 54,324,745 | |
| -1 | -54,324,745 |
Now, we try dividing 54,324,745 by 3:
54,324,745 ÷ 3 = 18,108,248.3333
If the quotient is a whole number, then 3 and 18,108,248.3333 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 | 54,324,745 | |
| -1 | -54,324,745 |
Let's try dividing by 4:
54,324,745 ÷ 4 = 13,581,186.25
If the quotient is a whole number, then 4 and 13,581,186.25 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 | 54,324,745 | |
| -1 | 54,324,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 83 | 395 | 415 | 1,657 | 6,557 | 8,285 | 32,785 | 130,903 | 137,531 | 654,515 | 687,655 | 10,864,949 | 54,324,745 |
| -1 | -5 | -79 | -83 | -395 | -415 | -1,657 | -6,557 | -8,285 | -32,785 | -130,903 | -137,531 | -654,515 | -687,655 | -10,864,949 | -54,324,745 |
