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 26,602,237, 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 | 26,602,237 | |
| -1 | -26,602,237 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,602,237.
Example:
1 x 26,602,237 = 26,602,237
and
-1 x -26,602,237 = 26,602,237
Notice both answers equal 26,602,237
With that explanation out of the way, let's continue. Next, we take the number 26,602,237 and divide it by 2:
26,602,237 ÷ 2 = 13,301,118.5
If the quotient is a whole number, then 2 and 13,301,118.5 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 | 26,602,237 | |
| -1 | -26,602,237 |
Now, we try dividing 26,602,237 by 3:
26,602,237 ÷ 3 = 8,867,412.3333
If the quotient is a whole number, then 3 and 8,867,412.3333 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 | 26,602,237 | |
| -1 | -26,602,237 |
Let's try dividing by 4:
26,602,237 ÷ 4 = 6,650,559.25
If the quotient is a whole number, then 4 and 6,650,559.25 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 | 26,602,237 | |
| -1 | 26,602,237 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 139 | 157 | 1,219 | 3,197 | 3,611 | 7,367 | 8,321 | 21,823 | 169,441 | 191,383 | 501,929 | 1,156,619 | 26,602,237 |
| -1 | -23 | -53 | -139 | -157 | -1,219 | -3,197 | -3,611 | -7,367 | -8,321 | -21,823 | -169,441 | -191,383 | -501,929 | -1,156,619 | -26,602,237 |
