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 13,195,763, 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 | 13,195,763 | |
| -1 | -13,195,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,195,763.
Example:
1 x 13,195,763 = 13,195,763
and
-1 x -13,195,763 = 13,195,763
Notice both answers equal 13,195,763
With that explanation out of the way, let's continue. Next, we take the number 13,195,763 and divide it by 2:
13,195,763 ÷ 2 = 6,597,881.5
If the quotient is a whole number, then 2 and 6,597,881.5 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 | 13,195,763 | |
| -1 | -13,195,763 |
Now, we try dividing 13,195,763 by 3:
13,195,763 ÷ 3 = 4,398,587.6667
If the quotient is a whole number, then 3 and 4,398,587.6667 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 | 13,195,763 | |
| -1 | -13,195,763 |
Let's try dividing by 4:
13,195,763 ÷ 4 = 3,298,940.75
If the quotient is a whole number, then 4 and 3,298,940.75 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 | 13,195,763 | |
| -1 | 13,195,763 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 89 | 359 | 413 | 623 | 2,513 | 5,251 | 21,181 | 31,951 | 36,757 | 148,267 | 223,657 | 1,885,109 | 13,195,763 |
| -1 | -7 | -59 | -89 | -359 | -413 | -623 | -2,513 | -5,251 | -21,181 | -31,951 | -36,757 | -148,267 | -223,657 | -1,885,109 | -13,195,763 |
