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 10,155,649, 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 | 10,155,649 | |
| -1 | -10,155,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,155,649.
Example:
1 x 10,155,649 = 10,155,649
and
-1 x -10,155,649 = 10,155,649
Notice both answers equal 10,155,649
With that explanation out of the way, let's continue. Next, we take the number 10,155,649 and divide it by 2:
10,155,649 ÷ 2 = 5,077,824.5
If the quotient is a whole number, then 2 and 5,077,824.5 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 | 10,155,649 | |
| -1 | -10,155,649 |
Now, we try dividing 10,155,649 by 3:
10,155,649 ÷ 3 = 3,385,216.3333
If the quotient is a whole number, then 3 and 3,385,216.3333 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 | 10,155,649 | |
| -1 | -10,155,649 |
Let's try dividing by 4:
10,155,649 ÷ 4 = 2,538,912.25
If the quotient is a whole number, then 4 and 2,538,912.25 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 | 10,155,649 | |
| -1 | 10,155,649 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 113 | 259 | 347 | 791 | 2,429 | 4,181 | 12,839 | 29,267 | 39,211 | 89,873 | 274,477 | 1,450,807 | 10,155,649 |
| -1 | -7 | -37 | -113 | -259 | -347 | -791 | -2,429 | -4,181 | -12,839 | -29,267 | -39,211 | -89,873 | -274,477 | -1,450,807 | -10,155,649 |
