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 13,475,077, 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 | 13,475,077 | |
| -1 | -13,475,077 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,475,077.
Example:
1 x 13,475,077 = 13,475,077
and
-1 x -13,475,077 = 13,475,077
Notice both answers equal 13,475,077
With that explanation out of the way, let's continue. Next, we take the number 13,475,077 and divide it by 2:
13,475,077 ÷ 2 = 6,737,538.5
If the quotient is a whole number, then 2 and 6,737,538.5 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 | 13,475,077 | |
| -1 | -13,475,077 |
Now, we try dividing 13,475,077 by 3:
13,475,077 ÷ 3 = 4,491,692.3333
If the quotient is a whole number, then 3 and 4,491,692.3333 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 | 13,475,077 | |
| -1 | -13,475,077 |
Let's try dividing by 4:
13,475,077 ÷ 4 = 3,368,769.25
If the quotient is a whole number, then 4 and 3,368,769.25 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 | 13,475,077 | |
| -1 | 13,475,077 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 139 | 973 | 1,259 | 1,529 | 8,813 | 10,703 | 13,849 | 96,943 | 175,001 | 1,225,007 | 1,925,011 | 13,475,077 |
| -1 | -7 | -11 | -77 | -139 | -973 | -1,259 | -1,529 | -8,813 | -10,703 | -13,849 | -96,943 | -175,001 | -1,225,007 | -1,925,011 | -13,475,077 |
