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 106,477,777, 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 | 106,477,777 | |
| -1 | -106,477,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 106,477,777.
Example:
1 x 106,477,777 = 106,477,777
and
-1 x -106,477,777 = 106,477,777
Notice both answers equal 106,477,777
With that explanation out of the way, let's continue. Next, we take the number 106,477,777 and divide it by 2:
106,477,777 ÷ 2 = 53,238,888.5
If the quotient is a whole number, then 2 and 53,238,888.5 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 | 106,477,777 | |
| -1 | -106,477,777 |
Now, we try dividing 106,477,777 by 3:
106,477,777 ÷ 3 = 35,492,592.3333
If the quotient is a whole number, then 3 and 35,492,592.3333 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 | 106,477,777 | |
| -1 | -106,477,777 |
Let's try dividing by 4:
106,477,777 ÷ 4 = 26,619,444.25
If the quotient is a whole number, then 4 and 26,619,444.25 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 | 106,477,777 | |
| -1 | 106,477,777 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 71 | 217 | 497 | 2,201 | 6,911 | 15,407 | 48,377 | 214,241 | 490,681 | 1,499,687 | 3,434,767 | 15,211,111 | 106,477,777 |
| -1 | -7 | -31 | -71 | -217 | -497 | -2,201 | -6,911 | -15,407 | -48,377 | -214,241 | -490,681 | -1,499,687 | -3,434,767 | -15,211,111 | -106,477,777 |
