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 151,441,117, 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 | 151,441,117 | |
| -1 | -151,441,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,441,117.
Example:
1 x 151,441,117 = 151,441,117
and
-1 x -151,441,117 = 151,441,117
Notice both answers equal 151,441,117
With that explanation out of the way, let's continue. Next, we take the number 151,441,117 and divide it by 2:
151,441,117 ÷ 2 = 75,720,558.5
If the quotient is a whole number, then 2 and 75,720,558.5 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 | 151,441,117 | |
| -1 | -151,441,117 |
Now, we try dividing 151,441,117 by 3:
151,441,117 ÷ 3 = 50,480,372.3333
If the quotient is a whole number, then 3 and 50,480,372.3333 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 | 151,441,117 | |
| -1 | -151,441,117 |
Let's try dividing by 4:
151,441,117 ÷ 4 = 37,860,279.25
If the quotient is a whole number, then 4 and 37,860,279.25 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 | 151,441,117 | |
| -1 | 151,441,117 |
If you did it right, you will end up with this table:
| 1 | 17 | 101 | 193 | 457 | 1,717 | 3,281 | 7,769 | 19,493 | 46,157 | 88,201 | 331,381 | 784,669 | 1,499,417 | 8,908,301 | 151,441,117 |
| -1 | -17 | -101 | -193 | -457 | -1,717 | -3,281 | -7,769 | -19,493 | -46,157 | -88,201 | -331,381 | -784,669 | -1,499,417 | -8,908,301 | -151,441,117 |
