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 22,137,689, 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 | 22,137,689 | |
| -1 | -22,137,689 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,137,689.
Example:
1 x 22,137,689 = 22,137,689
and
-1 x -22,137,689 = 22,137,689
Notice both answers equal 22,137,689
With that explanation out of the way, let's continue. Next, we take the number 22,137,689 and divide it by 2:
22,137,689 ÷ 2 = 11,068,844.5
If the quotient is a whole number, then 2 and 11,068,844.5 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 | 22,137,689 | |
| -1 | -22,137,689 |
Now, we try dividing 22,137,689 by 3:
22,137,689 ÷ 3 = 7,379,229.6667
If the quotient is a whole number, then 3 and 7,379,229.6667 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 | 22,137,689 | |
| -1 | -22,137,689 |
Let's try dividing by 4:
22,137,689 ÷ 4 = 5,534,422.25
If the quotient is a whole number, then 4 and 5,534,422.25 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 | 22,137,689 | |
| -1 | 22,137,689 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 31 | 119 | 217 | 289 | 353 | 527 | 2,023 | 2,471 | 3,689 | 6,001 | 8,959 | 10,943 | 42,007 | 62,713 | 76,601 | 102,017 | 186,031 | 714,119 | 1,302,217 | 3,162,527 | 22,137,689 |
| -1 | -7 | -17 | -31 | -119 | -217 | -289 | -353 | -527 | -2,023 | -2,471 | -3,689 | -6,001 | -8,959 | -10,943 | -42,007 | -62,713 | -76,601 | -102,017 | -186,031 | -714,119 | -1,302,217 | -3,162,527 | -22,137,689 |
