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 41,742,455, 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 | 41,742,455 | |
| -1 | -41,742,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,742,455.
Example:
1 x 41,742,455 = 41,742,455
and
-1 x -41,742,455 = 41,742,455
Notice both answers equal 41,742,455
With that explanation out of the way, let's continue. Next, we take the number 41,742,455 and divide it by 2:
41,742,455 ÷ 2 = 20,871,227.5
If the quotient is a whole number, then 2 and 20,871,227.5 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 | 41,742,455 | |
| -1 | -41,742,455 |
Now, we try dividing 41,742,455 by 3:
41,742,455 ÷ 3 = 13,914,151.6667
If the quotient is a whole number, then 3 and 13,914,151.6667 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 | 41,742,455 | |
| -1 | -41,742,455 |
Let's try dividing by 4:
41,742,455 ÷ 4 = 10,435,613.75
If the quotient is a whole number, then 4 and 10,435,613.75 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 | 41,742,455 | |
| -1 | 41,742,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 479 | 601 | 2,395 | 3,005 | 13,891 | 17,429 | 69,455 | 87,145 | 287,879 | 1,439,395 | 8,348,491 | 41,742,455 |
| -1 | -5 | -29 | -145 | -479 | -601 | -2,395 | -3,005 | -13,891 | -17,429 | -69,455 | -87,145 | -287,879 | -1,439,395 | -8,348,491 | -41,742,455 |
