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 66,264,565, 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 | 66,264,565 | |
| -1 | -66,264,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,264,565.
Example:
1 x 66,264,565 = 66,264,565
and
-1 x -66,264,565 = 66,264,565
Notice both answers equal 66,264,565
With that explanation out of the way, let's continue. Next, we take the number 66,264,565 and divide it by 2:
66,264,565 ÷ 2 = 33,132,282.5
If the quotient is a whole number, then 2 and 33,132,282.5 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 | 66,264,565 | |
| -1 | -66,264,565 |
Now, we try dividing 66,264,565 by 3:
66,264,565 ÷ 3 = 22,088,188.3333
If the quotient is a whole number, then 3 and 22,088,188.3333 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 | 66,264,565 | |
| -1 | -66,264,565 |
Let's try dividing by 4:
66,264,565 ÷ 4 = 16,566,141.25
If the quotient is a whole number, then 4 and 16,566,141.25 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 | 66,264,565 | |
| -1 | 66,264,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 107 | 145 | 535 | 3,103 | 4,271 | 15,515 | 21,355 | 123,859 | 456,997 | 619,295 | 2,284,985 | 13,252,913 | 66,264,565 |
| -1 | -5 | -29 | -107 | -145 | -535 | -3,103 | -4,271 | -15,515 | -21,355 | -123,859 | -456,997 | -619,295 | -2,284,985 | -13,252,913 | -66,264,565 |
