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 162,345,575, 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 | 162,345,575 | |
| -1 | -162,345,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,345,575.
Example:
1 x 162,345,575 = 162,345,575
and
-1 x -162,345,575 = 162,345,575
Notice both answers equal 162,345,575
With that explanation out of the way, let's continue. Next, we take the number 162,345,575 and divide it by 2:
162,345,575 ÷ 2 = 81,172,787.5
If the quotient is a whole number, then 2 and 81,172,787.5 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 | 162,345,575 | |
| -1 | -162,345,575 |
Now, we try dividing 162,345,575 by 3:
162,345,575 ÷ 3 = 54,115,191.6667
If the quotient is a whole number, then 3 and 54,115,191.6667 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 | 162,345,575 | |
| -1 | -162,345,575 |
Let's try dividing by 4:
162,345,575 ÷ 4 = 40,586,393.75
If the quotient is a whole number, then 4 and 40,586,393.75 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 | 162,345,575 | |
| -1 | 162,345,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 132,527 | 662,635 | 927,689 | 3,313,175 | 4,638,445 | 6,493,823 | 23,192,225 | 32,469,115 | 162,345,575 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -132,527 | -662,635 | -927,689 | -3,313,175 | -4,638,445 | -6,493,823 | -23,192,225 | -32,469,115 | -162,345,575 |
