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 54,400,549, 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 | 54,400,549 | |
| -1 | -54,400,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,400,549.
Example:
1 x 54,400,549 = 54,400,549
and
-1 x -54,400,549 = 54,400,549
Notice both answers equal 54,400,549
With that explanation out of the way, let's continue. Next, we take the number 54,400,549 and divide it by 2:
54,400,549 ÷ 2 = 27,200,274.5
If the quotient is a whole number, then 2 and 27,200,274.5 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 | 54,400,549 | |
| -1 | -54,400,549 |
Now, we try dividing 54,400,549 by 3:
54,400,549 ÷ 3 = 18,133,516.3333
If the quotient is a whole number, then 3 and 18,133,516.3333 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 | 54,400,549 | |
| -1 | -54,400,549 |
Let's try dividing by 4:
54,400,549 ÷ 4 = 13,600,137.25
If the quotient is a whole number, then 4 and 13,600,137.25 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 | 54,400,549 | |
| -1 | 54,400,549 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 73 | 203 | 511 | 2,117 | 3,671 | 14,819 | 25,697 | 106,459 | 267,983 | 745,213 | 1,875,881 | 7,771,507 | 54,400,549 |
| -1 | -7 | -29 | -73 | -203 | -511 | -2,117 | -3,671 | -14,819 | -25,697 | -106,459 | -267,983 | -745,213 | -1,875,881 | -7,771,507 | -54,400,549 |
