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 162,532,465, 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 | 162,532,465 | |
| -1 | -162,532,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,532,465.
Example:
1 x 162,532,465 = 162,532,465
and
-1 x -162,532,465 = 162,532,465
Notice both answers equal 162,532,465
With that explanation out of the way, let's continue. Next, we take the number 162,532,465 and divide it by 2:
162,532,465 ÷ 2 = 81,266,232.5
If the quotient is a whole number, then 2 and 81,266,232.5 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 | 162,532,465 | |
| -1 | -162,532,465 |
Now, we try dividing 162,532,465 by 3:
162,532,465 ÷ 3 = 54,177,488.3333
If the quotient is a whole number, then 3 and 54,177,488.3333 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 | 162,532,465 | |
| -1 | -162,532,465 |
Let's try dividing by 4:
162,532,465 ÷ 4 = 40,633,116.25
If the quotient is a whole number, then 4 and 40,633,116.25 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 | 162,532,465 | |
| -1 | 162,532,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 107 | 461 | 535 | 659 | 2,305 | 3,295 | 49,327 | 70,513 | 246,635 | 303,799 | 352,565 | 1,518,995 | 32,506,493 | 162,532,465 |
| -1 | -5 | -107 | -461 | -535 | -659 | -2,305 | -3,295 | -49,327 | -70,513 | -246,635 | -303,799 | -352,565 | -1,518,995 | -32,506,493 | -162,532,465 |
