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 65,374,775, 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 | 65,374,775 | |
| -1 | -65,374,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,374,775.
Example:
1 x 65,374,775 = 65,374,775
and
-1 x -65,374,775 = 65,374,775
Notice both answers equal 65,374,775
With that explanation out of the way, let's continue. Next, we take the number 65,374,775 and divide it by 2:
65,374,775 ÷ 2 = 32,687,387.5
If the quotient is a whole number, then 2 and 32,687,387.5 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 | 65,374,775 | |
| -1 | -65,374,775 |
Now, we try dividing 65,374,775 by 3:
65,374,775 ÷ 3 = 21,791,591.6667
If the quotient is a whole number, then 3 and 21,791,591.6667 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 | 65,374,775 | |
| -1 | -65,374,775 |
Let's try dividing by 4:
65,374,775 ÷ 4 = 16,343,693.75
If the quotient is a whole number, then 4 and 16,343,693.75 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 | 65,374,775 | |
| -1 | 65,374,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 101 | 425 | 505 | 1,523 | 1,717 | 2,525 | 7,615 | 8,585 | 25,891 | 38,075 | 42,925 | 129,455 | 153,823 | 647,275 | 769,115 | 2,614,991 | 3,845,575 | 13,074,955 | 65,374,775 |
| -1 | -5 | -17 | -25 | -85 | -101 | -425 | -505 | -1,523 | -1,717 | -2,525 | -7,615 | -8,585 | -25,891 | -38,075 | -42,925 | -129,455 | -153,823 | -647,275 | -769,115 | -2,614,991 | -3,845,575 | -13,074,955 | -65,374,775 |
