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 43,073,779, 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 | 43,073,779 | |
| -1 | -43,073,779 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,073,779.
Example:
1 x 43,073,779 = 43,073,779
and
-1 x -43,073,779 = 43,073,779
Notice both answers equal 43,073,779
With that explanation out of the way, let's continue. Next, we take the number 43,073,779 and divide it by 2:
43,073,779 ÷ 2 = 21,536,889.5
If the quotient is a whole number, then 2 and 21,536,889.5 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 | 43,073,779 | |
| -1 | -43,073,779 |
Now, we try dividing 43,073,779 by 3:
43,073,779 ÷ 3 = 14,357,926.3333
If the quotient is a whole number, then 3 and 14,357,926.3333 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 | 43,073,779 | |
| -1 | -43,073,779 |
Let's try dividing by 4:
43,073,779 ÷ 4 = 10,768,444.75
If the quotient is a whole number, then 4 and 10,768,444.75 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 | 43,073,779 | |
| -1 | 43,073,779 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 3,059 | 14,081 | 98,567 | 267,539 | 323,863 | 1,872,773 | 2,267,041 | 6,153,397 | 43,073,779 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -3,059 | -14,081 | -98,567 | -267,539 | -323,863 | -1,872,773 | -2,267,041 | -6,153,397 | -43,073,779 |
