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 78,526,357, 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 | 78,526,357 | |
| -1 | -78,526,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 78,526,357.
Example:
1 x 78,526,357 = 78,526,357
and
-1 x -78,526,357 = 78,526,357
Notice both answers equal 78,526,357
With that explanation out of the way, let's continue. Next, we take the number 78,526,357 and divide it by 2:
78,526,357 ÷ 2 = 39,263,178.5
If the quotient is a whole number, then 2 and 39,263,178.5 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 | 78,526,357 | |
| -1 | -78,526,357 |
Now, we try dividing 78,526,357 by 3:
78,526,357 ÷ 3 = 26,175,452.3333
If the quotient is a whole number, then 3 and 26,175,452.3333 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 | 78,526,357 | |
| -1 | -78,526,357 |
Let's try dividing by 4:
78,526,357 ÷ 4 = 19,631,589.25
If the quotient is a whole number, then 4 and 19,631,589.25 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 | 78,526,357 | |
| -1 | 78,526,357 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 41 | 91 | 169 | 287 | 533 | 1,183 | 1,619 | 3,731 | 6,929 | 11,333 | 21,047 | 48,503 | 66,379 | 147,329 | 273,611 | 464,653 | 862,927 | 1,915,277 | 6,040,489 | 11,218,051 | 78,526,357 |
| -1 | -7 | -13 | -41 | -91 | -169 | -287 | -533 | -1,183 | -1,619 | -3,731 | -6,929 | -11,333 | -21,047 | -48,503 | -66,379 | -147,329 | -273,611 | -464,653 | -862,927 | -1,915,277 | -6,040,489 | -11,218,051 | -78,526,357 |
