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 40,420,301, 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 | 40,420,301 | |
| -1 | -40,420,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,420,301.
Example:
1 x 40,420,301 = 40,420,301
and
-1 x -40,420,301 = 40,420,301
Notice both answers equal 40,420,301
With that explanation out of the way, let's continue. Next, we take the number 40,420,301 and divide it by 2:
40,420,301 ÷ 2 = 20,210,150.5
If the quotient is a whole number, then 2 and 20,210,150.5 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 | 40,420,301 | |
| -1 | -40,420,301 |
Now, we try dividing 40,420,301 by 3:
40,420,301 ÷ 3 = 13,473,433.6667
If the quotient is a whole number, then 3 and 13,473,433.6667 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 | 40,420,301 | |
| -1 | -40,420,301 |
Let's try dividing by 4:
40,420,301 ÷ 4 = 10,105,075.25
If the quotient is a whole number, then 4 and 10,105,075.25 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 | 40,420,301 | |
| -1 | 40,420,301 |
If you did it right, you will end up with this table:
| 1 | 41 | 43 | 101 | 227 | 1,763 | 4,141 | 4,343 | 9,307 | 9,761 | 22,927 | 178,063 | 400,201 | 940,007 | 985,861 | 40,420,301 |
| -1 | -41 | -43 | -101 | -227 | -1,763 | -4,141 | -4,343 | -9,307 | -9,761 | -22,927 | -178,063 | -400,201 | -940,007 | -985,861 | -40,420,301 |
