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 54,402,439, 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 | 54,402,439 | |
| -1 | -54,402,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,402,439.
Example:
1 x 54,402,439 = 54,402,439
and
-1 x -54,402,439 = 54,402,439
Notice both answers equal 54,402,439
With that explanation out of the way, let's continue. Next, we take the number 54,402,439 and divide it by 2:
54,402,439 ÷ 2 = 27,201,219.5
If the quotient is a whole number, then 2 and 27,201,219.5 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 | 54,402,439 | |
| -1 | -54,402,439 |
Now, we try dividing 54,402,439 by 3:
54,402,439 ÷ 3 = 18,134,146.3333
If the quotient is a whole number, then 3 and 18,134,146.3333 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 | 54,402,439 | |
| -1 | -54,402,439 |
Let's try dividing by 4:
54,402,439 ÷ 4 = 13,600,609.75
If the quotient is a whole number, then 4 and 13,600,609.75 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 | 54,402,439 | |
| -1 | 54,402,439 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 91 | 301 | 559 | 3,913 | 13,903 | 97,321 | 180,739 | 597,829 | 1,265,173 | 4,184,803 | 7,771,777 | 54,402,439 |
| -1 | -7 | -13 | -43 | -91 | -301 | -559 | -3,913 | -13,903 | -97,321 | -180,739 | -597,829 | -1,265,173 | -4,184,803 | -7,771,777 | -54,402,439 |
