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 65,475,425, 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 | 65,475,425 | |
| -1 | -65,475,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,475,425.
Example:
1 x 65,475,425 = 65,475,425
and
-1 x -65,475,425 = 65,475,425
Notice both answers equal 65,475,425
With that explanation out of the way, let's continue. Next, we take the number 65,475,425 and divide it by 2:
65,475,425 ÷ 2 = 32,737,712.5
If the quotient is a whole number, then 2 and 32,737,712.5 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 | 65,475,425 | |
| -1 | -65,475,425 |
Now, we try dividing 65,475,425 by 3:
65,475,425 ÷ 3 = 21,825,141.6667
If the quotient is a whole number, then 3 and 21,825,141.6667 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 | 65,475,425 | |
| -1 | -65,475,425 |
Let's try dividing by 4:
65,475,425 ÷ 4 = 16,368,856.25
If the quotient is a whole number, then 4 and 16,368,856.25 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 | 65,475,425 | |
| -1 | 65,475,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 307 | 449 | 475 | 1,535 | 2,245 | 5,833 | 7,675 | 8,531 | 11,225 | 29,165 | 42,655 | 137,843 | 145,825 | 213,275 | 689,215 | 2,619,017 | 3,446,075 | 13,095,085 | 65,475,425 |
| -1 | -5 | -19 | -25 | -95 | -307 | -449 | -475 | -1,535 | -2,245 | -5,833 | -7,675 | -8,531 | -11,225 | -29,165 | -42,655 | -137,843 | -145,825 | -213,275 | -689,215 | -2,619,017 | -3,446,075 | -13,095,085 | -65,475,425 |
