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 105,518,077, 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 | 105,518,077 | |
| -1 | -105,518,077 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,518,077.
Example:
1 x 105,518,077 = 105,518,077
and
-1 x -105,518,077 = 105,518,077
Notice both answers equal 105,518,077
With that explanation out of the way, let's continue. Next, we take the number 105,518,077 and divide it by 2:
105,518,077 ÷ 2 = 52,759,038.5
If the quotient is a whole number, then 2 and 52,759,038.5 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 | 105,518,077 | |
| -1 | -105,518,077 |
Now, we try dividing 105,518,077 by 3:
105,518,077 ÷ 3 = 35,172,692.3333
If the quotient is a whole number, then 3 and 35,172,692.3333 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 | 105,518,077 | |
| -1 | -105,518,077 |
Let's try dividing by 4:
105,518,077 ÷ 4 = 26,379,519.25
If the quotient is a whole number, then 4 and 26,379,519.25 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 | 105,518,077 | |
| -1 | 105,518,077 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 127 | 133 | 889 | 2,413 | 6,247 | 16,891 | 43,729 | 118,693 | 793,369 | 830,851 | 5,553,583 | 15,074,011 | 105,518,077 |
| -1 | -7 | -19 | -127 | -133 | -889 | -2,413 | -6,247 | -16,891 | -43,729 | -118,693 | -793,369 | -830,851 | -5,553,583 | -15,074,011 | -105,518,077 |
