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 78,861,335, 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 | 78,861,335 | |
| -1 | -78,861,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 78,861,335.
Example:
1 x 78,861,335 = 78,861,335
and
-1 x -78,861,335 = 78,861,335
Notice both answers equal 78,861,335
With that explanation out of the way, let's continue. Next, we take the number 78,861,335 and divide it by 2:
78,861,335 ÷ 2 = 39,430,667.5
If the quotient is a whole number, then 2 and 39,430,667.5 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 | 78,861,335 | |
| -1 | -78,861,335 |
Now, we try dividing 78,861,335 by 3:
78,861,335 ÷ 3 = 26,287,111.6667
If the quotient is a whole number, then 3 and 26,287,111.6667 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 | 78,861,335 | |
| -1 | -78,861,335 |
Let's try dividing by 4:
78,861,335 ÷ 4 = 19,715,333.75
If the quotient is a whole number, then 4 and 19,715,333.75 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 | 78,861,335 | |
| -1 | 78,861,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 409 | 787 | 2,045 | 2,863 | 3,935 | 5,509 | 14,315 | 20,041 | 27,545 | 38,563 | 100,205 | 192,815 | 321,883 | 1,609,415 | 2,253,181 | 11,265,905 | 15,772,267 | 78,861,335 |
| -1 | -5 | -7 | -35 | -49 | -245 | -409 | -787 | -2,045 | -2,863 | -3,935 | -5,509 | -14,315 | -20,041 | -27,545 | -38,563 | -100,205 | -192,815 | -321,883 | -1,609,415 | -2,253,181 | -11,265,905 | -15,772,267 | -78,861,335 |
