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 157,484,285, 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 | 157,484,285 | |
| -1 | -157,484,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 157,484,285.
Example:
1 x 157,484,285 = 157,484,285
and
-1 x -157,484,285 = 157,484,285
Notice both answers equal 157,484,285
With that explanation out of the way, let's continue. Next, we take the number 157,484,285 and divide it by 2:
157,484,285 ÷ 2 = 78,742,142.5
If the quotient is a whole number, then 2 and 78,742,142.5 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 | 157,484,285 | |
| -1 | -157,484,285 |
Now, we try dividing 157,484,285 by 3:
157,484,285 ÷ 3 = 52,494,761.6667
If the quotient is a whole number, then 3 and 52,494,761.6667 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 | 157,484,285 | |
| -1 | -157,484,285 |
Let's try dividing by 4:
157,484,285 ÷ 4 = 39,371,071.25
If the quotient is a whole number, then 4 and 39,371,071.25 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 | 157,484,285 | |
| -1 | 157,484,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 443 | 1,451 | 2,215 | 3,101 | 7,255 | 10,157 | 15,505 | 21,707 | 50,785 | 71,099 | 108,535 | 355,495 | 642,793 | 3,213,965 | 4,499,551 | 22,497,755 | 31,496,857 | 157,484,285 |
