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 162,445,435, 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 | 162,445,435 | |
| -1 | -162,445,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,445,435.
Example:
1 x 162,445,435 = 162,445,435
and
-1 x -162,445,435 = 162,445,435
Notice both answers equal 162,445,435
With that explanation out of the way, let's continue. Next, we take the number 162,445,435 and divide it by 2:
162,445,435 ÷ 2 = 81,222,717.5
If the quotient is a whole number, then 2 and 81,222,717.5 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 | 162,445,435 | |
| -1 | -162,445,435 |
Now, we try dividing 162,445,435 by 3:
162,445,435 ÷ 3 = 54,148,478.3333
If the quotient is a whole number, then 3 and 54,148,478.3333 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 | 162,445,435 | |
| -1 | -162,445,435 |
Let's try dividing by 4:
162,445,435 ÷ 4 = 40,611,358.75
If the quotient is a whole number, then 4 and 40,611,358.75 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 | 162,445,435 | |
| -1 | 162,445,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 313 | 1,565 | 4,513 | 7,199 | 22,565 | 35,995 | 103,799 | 518,995 | 1,412,569 | 7,062,845 | 32,489,087 | 162,445,435 |
| -1 | -5 | -23 | -115 | -313 | -1,565 | -4,513 | -7,199 | -22,565 | -35,995 | -103,799 | -518,995 | -1,412,569 | -7,062,845 | -32,489,087 | -162,445,435 |
