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 136,436,363, 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 | 136,436,363 | |
| -1 | -136,436,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,436,363.
Example:
1 x 136,436,363 = 136,436,363
and
-1 x -136,436,363 = 136,436,363
Notice both answers equal 136,436,363
With that explanation out of the way, let's continue. Next, we take the number 136,436,363 and divide it by 2:
136,436,363 ÷ 2 = 68,218,181.5
If the quotient is a whole number, then 2 and 68,218,181.5 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 | 136,436,363 | |
| -1 | -136,436,363 |
Now, we try dividing 136,436,363 by 3:
136,436,363 ÷ 3 = 45,478,787.6667
If the quotient is a whole number, then 3 and 45,478,787.6667 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 | 136,436,363 | |
| -1 | -136,436,363 |
Let's try dividing by 4:
136,436,363 ÷ 4 = 34,109,090.75
If the quotient is a whole number, then 4 and 34,109,090.75 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 | 136,436,363 | |
| -1 | 136,436,363 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 53 | 217 | 371 | 1,643 | 11,501 | 11,863 | 83,041 | 367,753 | 628,739 | 2,574,271 | 4,401,173 | 19,490,909 | 136,436,363 |
| -1 | -7 | -31 | -53 | -217 | -371 | -1,643 | -11,501 | -11,863 | -83,041 | -367,753 | -628,739 | -2,574,271 | -4,401,173 | -19,490,909 | -136,436,363 |
