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 11,420,635, 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 | 11,420,635 | |
| -1 | -11,420,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,420,635.
Example:
1 x 11,420,635 = 11,420,635
and
-1 x -11,420,635 = 11,420,635
Notice both answers equal 11,420,635
With that explanation out of the way, let's continue. Next, we take the number 11,420,635 and divide it by 2:
11,420,635 ÷ 2 = 5,710,317.5
If the quotient is a whole number, then 2 and 5,710,317.5 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 | 11,420,635 | |
| -1 | -11,420,635 |
Now, we try dividing 11,420,635 by 3:
11,420,635 ÷ 3 = 3,806,878.3333
If the quotient is a whole number, then 3 and 3,806,878.3333 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 | 11,420,635 | |
| -1 | -11,420,635 |
Let's try dividing by 4:
11,420,635 ÷ 4 = 2,855,158.75
If the quotient is a whole number, then 4 and 2,855,158.75 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 | 11,420,635 | |
| -1 | 11,420,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 79 | 145 | 395 | 997 | 2,291 | 4,985 | 11,455 | 28,913 | 78,763 | 144,565 | 393,815 | 2,284,127 | 11,420,635 |
| -1 | -5 | -29 | -79 | -145 | -395 | -997 | -2,291 | -4,985 | -11,455 | -28,913 | -78,763 | -144,565 | -393,815 | -2,284,127 | -11,420,635 |
