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 45,681,119, 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 | 45,681,119 | |
| -1 | -45,681,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,681,119.
Example:
1 x 45,681,119 = 45,681,119
and
-1 x -45,681,119 = 45,681,119
Notice both answers equal 45,681,119
With that explanation out of the way, let's continue. Next, we take the number 45,681,119 and divide it by 2:
45,681,119 ÷ 2 = 22,840,559.5
If the quotient is a whole number, then 2 and 22,840,559.5 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 | 45,681,119 | |
| -1 | -45,681,119 |
Now, we try dividing 45,681,119 by 3:
45,681,119 ÷ 3 = 15,227,039.6667
If the quotient is a whole number, then 3 and 15,227,039.6667 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 | 45,681,119 | |
| -1 | -45,681,119 |
Let's try dividing by 4:
45,681,119 ÷ 4 = 11,420,279.75
If the quotient is a whole number, then 4 and 11,420,279.75 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 | 45,681,119 | |
| -1 | 45,681,119 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 89 | 319 | 979 | 1,609 | 2,581 | 17,699 | 28,391 | 46,661 | 143,201 | 513,271 | 1,575,211 | 4,152,829 | 45,681,119 |
| -1 | -11 | -29 | -89 | -319 | -979 | -1,609 | -2,581 | -17,699 | -28,391 | -46,661 | -143,201 | -513,271 | -1,575,211 | -4,152,829 | -45,681,119 |
