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 13,779,731, 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 | 13,779,731 | |
| -1 | -13,779,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,779,731.
Example:
1 x 13,779,731 = 13,779,731
and
-1 x -13,779,731 = 13,779,731
Notice both answers equal 13,779,731
With that explanation out of the way, let's continue. Next, we take the number 13,779,731 and divide it by 2:
13,779,731 ÷ 2 = 6,889,865.5
If the quotient is a whole number, then 2 and 6,889,865.5 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 | 13,779,731 | |
| -1 | -13,779,731 |
Now, we try dividing 13,779,731 by 3:
13,779,731 ÷ 3 = 4,593,243.6667
If the quotient is a whole number, then 3 and 4,593,243.6667 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 | 13,779,731 | |
| -1 | -13,779,731 |
Let's try dividing by 4:
13,779,731 ÷ 4 = 3,444,932.75
If the quotient is a whole number, then 4 and 3,444,932.75 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 | 13,779,731 | |
| -1 | 13,779,731 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 41 | 49 | 133 | 287 | 361 | 779 | 931 | 2,009 | 2,527 | 5,453 | 6,859 | 14,801 | 17,689 | 38,171 | 48,013 | 103,607 | 281,219 | 336,091 | 725,249 | 1,968,533 | 13,779,731 |
| -1 | -7 | -19 | -41 | -49 | -133 | -287 | -361 | -779 | -931 | -2,009 | -2,527 | -5,453 | -6,859 | -14,801 | -17,689 | -38,171 | -48,013 | -103,607 | -281,219 | -336,091 | -725,249 | -1,968,533 | -13,779,731 |
