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 65,774,045, 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 | 65,774,045 | |
| -1 | -65,774,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,774,045.
Example:
1 x 65,774,045 = 65,774,045
and
-1 x -65,774,045 = 65,774,045
Notice both answers equal 65,774,045
With that explanation out of the way, let's continue. Next, we take the number 65,774,045 and divide it by 2:
65,774,045 ÷ 2 = 32,887,022.5
If the quotient is a whole number, then 2 and 32,887,022.5 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 | 65,774,045 | |
| -1 | -65,774,045 |
Now, we try dividing 65,774,045 by 3:
65,774,045 ÷ 3 = 21,924,681.6667
If the quotient is a whole number, then 3 and 21,924,681.6667 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 | 65,774,045 | |
| -1 | -65,774,045 |
Let's try dividing by 4:
65,774,045 ÷ 4 = 16,443,511.25
If the quotient is a whole number, then 4 and 16,443,511.25 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 | 65,774,045 | |
| -1 | 65,774,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 71 | 205 | 355 | 2,911 | 4,519 | 14,555 | 22,595 | 185,279 | 320,849 | 926,395 | 1,604,245 | 13,154,809 | 65,774,045 |
| -1 | -5 | -41 | -71 | -205 | -355 | -2,911 | -4,519 | -14,555 | -22,595 | -185,279 | -320,849 | -926,395 | -1,604,245 | -13,154,809 | -65,774,045 |
