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 151,046,555, 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 | 151,046,555 | |
| -1 | -151,046,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,046,555.
Example:
1 x 151,046,555 = 151,046,555
and
-1 x -151,046,555 = 151,046,555
Notice both answers equal 151,046,555
With that explanation out of the way, let's continue. Next, we take the number 151,046,555 and divide it by 2:
151,046,555 ÷ 2 = 75,523,277.5
If the quotient is a whole number, then 2 and 75,523,277.5 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 | 151,046,555 | |
| -1 | -151,046,555 |
Now, we try dividing 151,046,555 by 3:
151,046,555 ÷ 3 = 50,348,851.6667
If the quotient is a whole number, then 3 and 50,348,851.6667 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 | 151,046,555 | |
| -1 | -151,046,555 |
Let's try dividing by 4:
151,046,555 ÷ 4 = 37,761,638.75
If the quotient is a whole number, then 4 and 37,761,638.75 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 | 151,046,555 | |
| -1 | 151,046,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 51,817 | 259,085 | 569,987 | 2,746,301 | 2,849,935 | 13,731,505 | 30,209,311 | 151,046,555 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -51,817 | -259,085 | -569,987 | -2,746,301 | -2,849,935 | -13,731,505 | -30,209,311 | -151,046,555 |
