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 631,652,245, 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 | 631,652,245 | |
| -1 | -631,652,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 631,652,245.
Example:
1 x 631,652,245 = 631,652,245
and
-1 x -631,652,245 = 631,652,245
Notice both answers equal 631,652,245
With that explanation out of the way, let's continue. Next, we take the number 631,652,245 and divide it by 2:
631,652,245 ÷ 2 = 315,826,122.5
If the quotient is a whole number, then 2 and 315,826,122.5 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 | 631,652,245 | |
| -1 | -631,652,245 |
Now, we try dividing 631,652,245 by 3:
631,652,245 ÷ 3 = 210,550,748.3333
If the quotient is a whole number, then 3 and 210,550,748.3333 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 | 631,652,245 | |
| -1 | -631,652,245 |
Let's try dividing by 4:
631,652,245 ÷ 4 = 157,913,061.25
If the quotient is a whole number, then 4 and 157,913,061.25 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 | 631,652,245 | |
| -1 | 631,652,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 949,853 | 4,749,265 | 6,648,971 | 18,047,207 | 33,244,855 | 90,236,035 | 126,330,449 | 631,652,245 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -949,853 | -4,749,265 | -6,648,971 | -18,047,207 | -33,244,855 | -90,236,035 | -126,330,449 | -631,652,245 |
