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 151,026,827, 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 | 151,026,827 | |
| -1 | -151,026,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,026,827.
Example:
1 x 151,026,827 = 151,026,827
and
-1 x -151,026,827 = 151,026,827
Notice both answers equal 151,026,827
With that explanation out of the way, let's continue. Next, we take the number 151,026,827 and divide it by 2:
151,026,827 ÷ 2 = 75,513,413.5
If the quotient is a whole number, then 2 and 75,513,413.5 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 | 151,026,827 | |
| -1 | -151,026,827 |
Now, we try dividing 151,026,827 by 3:
151,026,827 ÷ 3 = 50,342,275.6667
If the quotient is a whole number, then 3 and 50,342,275.6667 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 | 151,026,827 | |
| -1 | -151,026,827 |
Let's try dividing by 4:
151,026,827 ÷ 4 = 37,756,706.75
If the quotient is a whole number, then 4 and 37,756,706.75 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 | 151,026,827 | |
| -1 | 151,026,827 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 461 | 2,753 | 3,227 | 7,837 | 19,271 | 46,801 | 54,859 | 327,607 | 1,269,133 | 8,883,931 | 21,575,261 | 151,026,827 |
| -1 | -7 | -17 | -119 | -461 | -2,753 | -3,227 | -7,837 | -19,271 | -46,801 | -54,859 | -327,607 | -1,269,133 | -8,883,931 | -21,575,261 | -151,026,827 |
