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 13,429,639, 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 | 13,429,639 | |
| -1 | -13,429,639 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,429,639.
Example:
1 x 13,429,639 = 13,429,639
and
-1 x -13,429,639 = 13,429,639
Notice both answers equal 13,429,639
With that explanation out of the way, let's continue. Next, we take the number 13,429,639 and divide it by 2:
13,429,639 ÷ 2 = 6,714,819.5
If the quotient is a whole number, then 2 and 6,714,819.5 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 | 13,429,639 | |
| -1 | -13,429,639 |
Now, we try dividing 13,429,639 by 3:
13,429,639 ÷ 3 = 4,476,546.3333
If the quotient is a whole number, then 3 and 4,476,546.3333 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 | 13,429,639 | |
| -1 | -13,429,639 |
Let's try dividing by 4:
13,429,639 ÷ 4 = 3,357,409.75
If the quotient is a whole number, then 4 and 3,357,409.75 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 | 13,429,639 | |
| -1 | 13,429,639 |
If you did it right, you will end up with this table:
| 1 | 29 | 47 | 59 | 167 | 1,363 | 1,711 | 2,773 | 4,843 | 7,849 | 9,853 | 80,417 | 227,621 | 285,737 | 463,091 | 13,429,639 |
| -1 | -29 | -47 | -59 | -167 | -1,363 | -1,711 | -2,773 | -4,843 | -7,849 | -9,853 | -80,417 | -227,621 | -285,737 | -463,091 | -13,429,639 |
