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 83,078,303, 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 | 83,078,303 | |
| -1 | -83,078,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,078,303.
Example:
1 x 83,078,303 = 83,078,303
and
-1 x -83,078,303 = 83,078,303
Notice both answers equal 83,078,303
With that explanation out of the way, let's continue. Next, we take the number 83,078,303 and divide it by 2:
83,078,303 ÷ 2 = 41,539,151.5
If the quotient is a whole number, then 2 and 41,539,151.5 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 | 83,078,303 | |
| -1 | -83,078,303 |
Now, we try dividing 83,078,303 by 3:
83,078,303 ÷ 3 = 27,692,767.6667
If the quotient is a whole number, then 3 and 27,692,767.6667 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 | 83,078,303 | |
| -1 | -83,078,303 |
Let's try dividing by 4:
83,078,303 ÷ 4 = 20,769,575.75
If the quotient is a whole number, then 4 and 20,769,575.75 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 | 83,078,303 | |
| -1 | 83,078,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 63,467 | 444,269 | 698,137 | 1,078,939 | 4,886,959 | 7,552,573 | 11,868,329 | 83,078,303 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -63,467 | -444,269 | -698,137 | -1,078,939 | -4,886,959 | -7,552,573 | -11,868,329 | -83,078,303 |
