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 54,128,225, 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 | 54,128,225 | |
| -1 | -54,128,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,128,225.
Example:
1 x 54,128,225 = 54,128,225
and
-1 x -54,128,225 = 54,128,225
Notice both answers equal 54,128,225
With that explanation out of the way, let's continue. Next, we take the number 54,128,225 and divide it by 2:
54,128,225 ÷ 2 = 27,064,112.5
If the quotient is a whole number, then 2 and 27,064,112.5 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 | 54,128,225 | |
| -1 | -54,128,225 |
Now, we try dividing 54,128,225 by 3:
54,128,225 ÷ 3 = 18,042,741.6667
If the quotient is a whole number, then 3 and 18,042,741.6667 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 | 54,128,225 | |
| -1 | -54,128,225 |
Let's try dividing by 4:
54,128,225 ÷ 4 = 13,532,056.25
If the quotient is a whole number, then 4 and 13,532,056.25 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 | 54,128,225 | |
| -1 | 54,128,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 163 | 185 | 359 | 815 | 925 | 1,795 | 4,075 | 6,031 | 8,975 | 13,283 | 30,155 | 58,517 | 66,415 | 150,775 | 292,585 | 332,075 | 1,462,925 | 2,165,129 | 10,825,645 | 54,128,225 |
| -1 | -5 | -25 | -37 | -163 | -185 | -359 | -815 | -925 | -1,795 | -4,075 | -6,031 | -8,975 | -13,283 | -30,155 | -58,517 | -66,415 | -150,775 | -292,585 | -332,075 | -1,462,925 | -2,165,129 | -10,825,645 | -54,128,225 |
