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 110,740,861, 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 | 110,740,861 | |
| -1 | -110,740,861 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,740,861.
Example:
1 x 110,740,861 = 110,740,861
and
-1 x -110,740,861 = 110,740,861
Notice both answers equal 110,740,861
With that explanation out of the way, let's continue. Next, we take the number 110,740,861 and divide it by 2:
110,740,861 ÷ 2 = 55,370,430.5
If the quotient is a whole number, then 2 and 55,370,430.5 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 | 110,740,861 | |
| -1 | -110,740,861 |
Now, we try dividing 110,740,861 by 3:
110,740,861 ÷ 3 = 36,913,620.3333
If the quotient is a whole number, then 3 and 36,913,620.3333 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 | 110,740,861 | |
| -1 | -110,740,861 |
Let's try dividing by 4:
110,740,861 ÷ 4 = 27,685,215.25
If the quotient is a whole number, then 4 and 27,685,215.25 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 | 110,740,861 | |
| -1 | 110,740,861 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 601 | 2,393 | 4,207 | 6,611 | 16,751 | 26,323 | 46,277 | 184,261 | 1,438,193 | 10,067,351 | 15,820,123 | 110,740,861 |
| -1 | -7 | -11 | -77 | -601 | -2,393 | -4,207 | -6,611 | -16,751 | -26,323 | -46,277 | -184,261 | -1,438,193 | -10,067,351 | -15,820,123 | -110,740,861 |
