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 135,232,867, 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 | 135,232,867 | |
| -1 | -135,232,867 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,232,867.
Example:
1 x 135,232,867 = 135,232,867
and
-1 x -135,232,867 = 135,232,867
Notice both answers equal 135,232,867
With that explanation out of the way, let's continue. Next, we take the number 135,232,867 and divide it by 2:
135,232,867 ÷ 2 = 67,616,433.5
If the quotient is a whole number, then 2 and 67,616,433.5 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 | 135,232,867 | |
| -1 | -135,232,867 |
Now, we try dividing 135,232,867 by 3:
135,232,867 ÷ 3 = 45,077,622.3333
If the quotient is a whole number, then 3 and 45,077,622.3333 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 | 135,232,867 | |
| -1 | -135,232,867 |
Let's try dividing by 4:
135,232,867 ÷ 4 = 33,808,216.75
If the quotient is a whole number, then 4 and 33,808,216.75 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 | 135,232,867 | |
| -1 | 135,232,867 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 121 | 469 | 737 | 847 | 2,383 | 5,159 | 8,107 | 16,681 | 26,213 | 56,749 | 159,661 | 183,491 | 288,343 | 1,117,627 | 1,756,271 | 2,018,401 | 12,293,897 | 19,318,981 | 135,232,867 |
| -1 | -7 | -11 | -67 | -77 | -121 | -469 | -737 | -847 | -2,383 | -5,159 | -8,107 | -16,681 | -26,213 | -56,749 | -159,661 | -183,491 | -288,343 | -1,117,627 | -1,756,271 | -2,018,401 | -12,293,897 | -19,318,981 | -135,232,867 |
