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 160,151,047, 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 | 160,151,047 | |
| -1 | -160,151,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,151,047.
Example:
1 x 160,151,047 = 160,151,047
and
-1 x -160,151,047 = 160,151,047
Notice both answers equal 160,151,047
With that explanation out of the way, let's continue. Next, we take the number 160,151,047 and divide it by 2:
160,151,047 ÷ 2 = 80,075,523.5
If the quotient is a whole number, then 2 and 80,075,523.5 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 | 160,151,047 | |
| -1 | -160,151,047 |
Now, we try dividing 160,151,047 by 3:
160,151,047 ÷ 3 = 53,383,682.3333
If the quotient is a whole number, then 3 and 53,383,682.3333 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 | 160,151,047 | |
| -1 | -160,151,047 |
Let's try dividing by 4:
160,151,047 ÷ 4 = 40,037,761.75
If the quotient is a whole number, then 4 and 40,037,761.75 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 | 160,151,047 | |
| -1 | 160,151,047 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 61 | 161 | 427 | 529 | 709 | 1,403 | 3,703 | 4,963 | 9,821 | 16,307 | 32,269 | 43,249 | 114,149 | 225,883 | 302,743 | 375,061 | 994,727 | 2,625,427 | 6,963,089 | 22,878,721 | 160,151,047 |
| -1 | -7 | -23 | -61 | -161 | -427 | -529 | -709 | -1,403 | -3,703 | -4,963 | -9,821 | -16,307 | -32,269 | -43,249 | -114,149 | -225,883 | -302,743 | -375,061 | -994,727 | -2,625,427 | -6,963,089 | -22,878,721 | -160,151,047 |
