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 41,351,765, 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 | 41,351,765 | |
| -1 | -41,351,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,351,765.
Example:
1 x 41,351,765 = 41,351,765
and
-1 x -41,351,765 = 41,351,765
Notice both answers equal 41,351,765
With that explanation out of the way, let's continue. Next, we take the number 41,351,765 and divide it by 2:
41,351,765 ÷ 2 = 20,675,882.5
If the quotient is a whole number, then 2 and 20,675,882.5 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 | 41,351,765 | |
| -1 | -41,351,765 |
Now, we try dividing 41,351,765 by 3:
41,351,765 ÷ 3 = 13,783,921.6667
If the quotient is a whole number, then 3 and 13,783,921.6667 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 | 41,351,765 | |
| -1 | -41,351,765 |
Let's try dividing by 4:
41,351,765 ÷ 4 = 10,337,941.25
If the quotient is a whole number, then 4 and 10,337,941.25 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 | 41,351,765 | |
| -1 | 41,351,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 5,915 | 6,991 | 34,955 | 48,937 | 90,883 | 244,685 | 454,415 | 636,181 | 1,181,479 | 3,180,905 | 5,907,395 | 8,270,353 | 41,351,765 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -5,915 | -6,991 | -34,955 | -48,937 | -90,883 | -244,685 | -454,415 | -636,181 | -1,181,479 | -3,180,905 | -5,907,395 | -8,270,353 | -41,351,765 |
