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 16,134,937, 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 | 16,134,937 | |
| -1 | -16,134,937 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,134,937.
Example:
1 x 16,134,937 = 16,134,937
and
-1 x -16,134,937 = 16,134,937
Notice both answers equal 16,134,937
With that explanation out of the way, let's continue. Next, we take the number 16,134,937 and divide it by 2:
16,134,937 ÷ 2 = 8,067,468.5
If the quotient is a whole number, then 2 and 8,067,468.5 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 | 16,134,937 | |
| -1 | -16,134,937 |
Now, we try dividing 16,134,937 by 3:
16,134,937 ÷ 3 = 5,378,312.3333
If the quotient is a whole number, then 3 and 5,378,312.3333 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 | 16,134,937 | |
| -1 | -16,134,937 |
Let's try dividing by 4:
16,134,937 ÷ 4 = 4,033,734.25
If the quotient is a whole number, then 4 and 4,033,734.25 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 | 16,134,937 | |
| -1 | 16,134,937 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 169 | 299 | 593 | 1,183 | 2,093 | 3,887 | 4,151 | 7,709 | 13,639 | 27,209 | 53,963 | 95,473 | 100,217 | 177,307 | 701,519 | 1,241,149 | 2,304,991 | 16,134,937 |
| -1 | -7 | -13 | -23 | -91 | -161 | -169 | -299 | -593 | -1,183 | -2,093 | -3,887 | -4,151 | -7,709 | -13,639 | -27,209 | -53,963 | -95,473 | -100,217 | -177,307 | -701,519 | -1,241,149 | -2,304,991 | -16,134,937 |
