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 54,658,649, 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 | 54,658,649 | |
| -1 | -54,658,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,658,649.
Example:
1 x 54,658,649 = 54,658,649
and
-1 x -54,658,649 = 54,658,649
Notice both answers equal 54,658,649
With that explanation out of the way, let's continue. Next, we take the number 54,658,649 and divide it by 2:
54,658,649 ÷ 2 = 27,329,324.5
If the quotient is a whole number, then 2 and 27,329,324.5 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 | 54,658,649 | |
| -1 | -54,658,649 |
Now, we try dividing 54,658,649 by 3:
54,658,649 ÷ 3 = 18,219,549.6667
If the quotient is a whole number, then 3 and 18,219,549.6667 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 | 54,658,649 | |
| -1 | -54,658,649 |
Let's try dividing by 4:
54,658,649 ÷ 4 = 13,664,662.25
If the quotient is a whole number, then 4 and 13,664,662.25 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 | 54,658,649 | |
| -1 | 54,658,649 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 29 | 227 | 361 | 437 | 551 | 667 | 4,313 | 5,221 | 6,583 | 8,303 | 10,469 | 12,673 | 81,947 | 99,199 | 125,077 | 151,409 | 240,787 | 1,884,781 | 2,376,463 | 2,876,771 | 54,658,649 |
| -1 | -19 | -23 | -29 | -227 | -361 | -437 | -551 | -667 | -4,313 | -5,221 | -6,583 | -8,303 | -10,469 | -12,673 | -81,947 | -99,199 | -125,077 | -151,409 | -240,787 | -1,884,781 | -2,376,463 | -2,876,771 | -54,658,649 |
