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 660,401,245, 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 | 660,401,245 | |
| -1 | -660,401,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 660,401,245.
Example:
1 x 660,401,245 = 660,401,245
and
-1 x -660,401,245 = 660,401,245
Notice both answers equal 660,401,245
With that explanation out of the way, let's continue. Next, we take the number 660,401,245 and divide it by 2:
660,401,245 ÷ 2 = 330,200,622.5
If the quotient is a whole number, then 2 and 330,200,622.5 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 | 660,401,245 | |
| -1 | -660,401,245 |
Now, we try dividing 660,401,245 by 3:
660,401,245 ÷ 3 = 220,133,748.3333
If the quotient is a whole number, then 3 and 220,133,748.3333 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 | 660,401,245 | |
| -1 | -660,401,245 |
Let's try dividing by 4:
660,401,245 ÷ 4 = 165,100,311.25
If the quotient is a whole number, then 4 and 165,100,311.25 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 | 660,401,245 | |
| -1 | 660,401,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 67 | 335 | 469 | 2,345 | 281,621 | 1,408,105 | 1,971,347 | 9,856,735 | 18,868,607 | 94,343,035 | 132,080,249 | 660,401,245 |
| -1 | -5 | -7 | -35 | -67 | -335 | -469 | -2,345 | -281,621 | -1,408,105 | -1,971,347 | -9,856,735 | -18,868,607 | -94,343,035 | -132,080,249 | -660,401,245 |
