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 162,714,157, 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 | 162,714,157 | |
| -1 | -162,714,157 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,714,157.
Example:
1 x 162,714,157 = 162,714,157
and
-1 x -162,714,157 = 162,714,157
Notice both answers equal 162,714,157
With that explanation out of the way, let's continue. Next, we take the number 162,714,157 and divide it by 2:
162,714,157 ÷ 2 = 81,357,078.5
If the quotient is a whole number, then 2 and 81,357,078.5 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 | 162,714,157 | |
| -1 | -162,714,157 |
Now, we try dividing 162,714,157 by 3:
162,714,157 ÷ 3 = 54,238,052.3333
If the quotient is a whole number, then 3 and 54,238,052.3333 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 | 162,714,157 | |
| -1 | -162,714,157 |
Let's try dividing by 4:
162,714,157 ÷ 4 = 40,678,539.25
If the quotient is a whole number, then 4 and 40,678,539.25 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 | 162,714,157 | |
| -1 | 162,714,157 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 29 | 323 | 493 | 551 | 599 | 841 | 9,367 | 10,183 | 11,381 | 14,297 | 15,979 | 17,371 | 193,477 | 271,643 | 295,307 | 330,049 | 503,759 | 5,610,833 | 8,563,903 | 9,571,421 | 162,714,157 |
| -1 | -17 | -19 | -29 | -323 | -493 | -551 | -599 | -841 | -9,367 | -10,183 | -11,381 | -14,297 | -15,979 | -17,371 | -193,477 | -271,643 | -295,307 | -330,049 | -503,759 | -5,610,833 | -8,563,903 | -9,571,421 | -162,714,157 |
