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 78,503,035, 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 | 78,503,035 | |
| -1 | -78,503,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 78,503,035.
Example:
1 x 78,503,035 = 78,503,035
and
-1 x -78,503,035 = 78,503,035
Notice both answers equal 78,503,035
With that explanation out of the way, let's continue. Next, we take the number 78,503,035 and divide it by 2:
78,503,035 ÷ 2 = 39,251,517.5
If the quotient is a whole number, then 2 and 39,251,517.5 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 | 78,503,035 | |
| -1 | -78,503,035 |
Now, we try dividing 78,503,035 by 3:
78,503,035 ÷ 3 = 26,167,678.3333
If the quotient is a whole number, then 3 and 26,167,678.3333 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 | 78,503,035 | |
| -1 | -78,503,035 |
Let's try dividing by 4:
78,503,035 ÷ 4 = 19,625,758.75
If the quotient is a whole number, then 4 and 19,625,758.75 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 | 78,503,035 | |
| -1 | 78,503,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 169 | 305 | 793 | 845 | 1,523 | 3,965 | 7,615 | 10,309 | 19,799 | 51,545 | 92,903 | 98,995 | 257,387 | 464,515 | 1,207,739 | 1,286,935 | 6,038,695 | 15,700,607 | 78,503,035 |
| -1 | -5 | -13 | -61 | -65 | -169 | -305 | -793 | -845 | -1,523 | -3,965 | -7,615 | -10,309 | -19,799 | -51,545 | -92,903 | -98,995 | -257,387 | -464,515 | -1,207,739 | -1,286,935 | -6,038,695 | -15,700,607 | -78,503,035 |
