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 45,114,145, 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 | 45,114,145 | |
| -1 | -45,114,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,114,145.
Example:
1 x 45,114,145 = 45,114,145
and
-1 x -45,114,145 = 45,114,145
Notice both answers equal 45,114,145
With that explanation out of the way, let's continue. Next, we take the number 45,114,145 and divide it by 2:
45,114,145 ÷ 2 = 22,557,072.5
If the quotient is a whole number, then 2 and 22,557,072.5 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 | 45,114,145 | |
| -1 | -45,114,145 |
Now, we try dividing 45,114,145 by 3:
45,114,145 ÷ 3 = 15,038,048.3333
If the quotient is a whole number, then 3 and 15,038,048.3333 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 | 45,114,145 | |
| -1 | -45,114,145 |
Let's try dividing by 4:
45,114,145 ÷ 4 = 11,278,536.25
If the quotient is a whole number, then 4 and 11,278,536.25 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 | 45,114,145 | |
| -1 | 45,114,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 41 | 155 | 205 | 229 | 961 | 1,145 | 1,271 | 4,805 | 6,355 | 7,099 | 9,389 | 35,495 | 39,401 | 46,945 | 197,005 | 220,069 | 291,059 | 1,100,345 | 1,455,295 | 9,022,829 | 45,114,145 |
| -1 | -5 | -31 | -41 | -155 | -205 | -229 | -961 | -1,145 | -1,271 | -4,805 | -6,355 | -7,099 | -9,389 | -35,495 | -39,401 | -46,945 | -197,005 | -220,069 | -291,059 | -1,100,345 | -1,455,295 | -9,022,829 | -45,114,145 |
