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 65,261,525, 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 | 65,261,525 | |
| -1 | -65,261,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,261,525.
Example:
1 x 65,261,525 = 65,261,525
and
-1 x -65,261,525 = 65,261,525
Notice both answers equal 65,261,525
With that explanation out of the way, let's continue. Next, we take the number 65,261,525 and divide it by 2:
65,261,525 ÷ 2 = 32,630,762.5
If the quotient is a whole number, then 2 and 32,630,762.5 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 | 65,261,525 | |
| -1 | -65,261,525 |
Now, we try dividing 65,261,525 by 3:
65,261,525 ÷ 3 = 21,753,841.6667
If the quotient is a whole number, then 3 and 21,753,841.6667 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 | 65,261,525 | |
| -1 | -65,261,525 |
Let's try dividing by 4:
65,261,525 ÷ 4 = 16,315,381.25
If the quotient is a whole number, then 4 and 16,315,381.25 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 | 65,261,525 | |
| -1 | 65,261,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 37 | 175 | 185 | 259 | 925 | 1,295 | 6,475 | 10,079 | 50,395 | 70,553 | 251,975 | 352,765 | 372,923 | 1,763,825 | 1,864,615 | 2,610,461 | 9,323,075 | 13,052,305 | 65,261,525 |
| -1 | -5 | -7 | -25 | -35 | -37 | -175 | -185 | -259 | -925 | -1,295 | -6,475 | -10,079 | -50,395 | -70,553 | -251,975 | -352,765 | -372,923 | -1,763,825 | -1,864,615 | -2,610,461 | -9,323,075 | -13,052,305 | -65,261,525 |
