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 45,340,547, 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 | 45,340,547 | |
| -1 | -45,340,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,340,547.
Example:
1 x 45,340,547 = 45,340,547
and
-1 x -45,340,547 = 45,340,547
Notice both answers equal 45,340,547
With that explanation out of the way, let's continue. Next, we take the number 45,340,547 and divide it by 2:
45,340,547 ÷ 2 = 22,670,273.5
If the quotient is a whole number, then 2 and 22,670,273.5 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 | 45,340,547 | |
| -1 | -45,340,547 |
Now, we try dividing 45,340,547 by 3:
45,340,547 ÷ 3 = 15,113,515.6667
If the quotient is a whole number, then 3 and 15,113,515.6667 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 | 45,340,547 | |
| -1 | -45,340,547 |
Let's try dividing by 4:
45,340,547 ÷ 4 = 11,335,136.75
If the quotient is a whole number, then 4 and 11,335,136.75 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 | 45,340,547 | |
| -1 | 45,340,547 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 41 | 119 | 287 | 697 | 4,879 | 9,293 | 65,051 | 157,981 | 381,013 | 1,105,867 | 2,667,091 | 6,477,221 | 45,340,547 |
| -1 | -7 | -17 | -41 | -119 | -287 | -697 | -4,879 | -9,293 | -65,051 | -157,981 | -381,013 | -1,105,867 | -2,667,091 | -6,477,221 | -45,340,547 |
