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 65,354,555, 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 | 65,354,555 | |
| -1 | -65,354,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,354,555.
Example:
1 x 65,354,555 = 65,354,555
and
-1 x -65,354,555 = 65,354,555
Notice both answers equal 65,354,555
With that explanation out of the way, let's continue. Next, we take the number 65,354,555 and divide it by 2:
65,354,555 ÷ 2 = 32,677,277.5
If the quotient is a whole number, then 2 and 32,677,277.5 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 | 65,354,555 | |
| -1 | -65,354,555 |
Now, we try dividing 65,354,555 by 3:
65,354,555 ÷ 3 = 21,784,851.6667
If the quotient is a whole number, then 3 and 21,784,851.6667 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 | 65,354,555 | |
| -1 | -65,354,555 |
Let's try dividing by 4:
65,354,555 ÷ 4 = 16,338,638.75
If the quotient is a whole number, then 4 and 16,338,638.75 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 | 65,354,555 | |
| -1 | 65,354,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 491 | 2,455 | 3,437 | 3,803 | 17,185 | 19,015 | 26,621 | 133,105 | 1,867,273 | 9,336,365 | 13,070,911 | 65,354,555 |
| -1 | -5 | -7 | -35 | -491 | -2,455 | -3,437 | -3,803 | -17,185 | -19,015 | -26,621 | -133,105 | -1,867,273 | -9,336,365 | -13,070,911 | -65,354,555 |
