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 18,495,953, 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 | 18,495,953 | |
| -1 | -18,495,953 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,495,953.
Example:
1 x 18,495,953 = 18,495,953
and
-1 x -18,495,953 = 18,495,953
Notice both answers equal 18,495,953
With that explanation out of the way, let's continue. Next, we take the number 18,495,953 and divide it by 2:
18,495,953 ÷ 2 = 9,247,976.5
If the quotient is a whole number, then 2 and 9,247,976.5 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 | 18,495,953 | |
| -1 | -18,495,953 |
Now, we try dividing 18,495,953 by 3:
18,495,953 ÷ 3 = 6,165,317.6667
If the quotient is a whole number, then 3 and 6,165,317.6667 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 | 18,495,953 | |
| -1 | -18,495,953 |
Let's try dividing by 4:
18,495,953 ÷ 4 = 4,623,988.25
If the quotient is a whole number, then 4 and 4,623,988.25 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 | 18,495,953 | |
| -1 | 18,495,953 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 113 | 349 | 469 | 791 | 2,443 | 7,571 | 23,383 | 39,437 | 52,997 | 163,681 | 276,059 | 2,642,279 | 18,495,953 |
| -1 | -7 | -67 | -113 | -349 | -469 | -791 | -2,443 | -7,571 | -23,383 | -39,437 | -52,997 | -163,681 | -276,059 | -2,642,279 | -18,495,953 |
