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 151,126,537, 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 | 151,126,537 | |
| -1 | -151,126,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,126,537.
Example:
1 x 151,126,537 = 151,126,537
and
-1 x -151,126,537 = 151,126,537
Notice both answers equal 151,126,537
With that explanation out of the way, let's continue. Next, we take the number 151,126,537 and divide it by 2:
151,126,537 ÷ 2 = 75,563,268.5
If the quotient is a whole number, then 2 and 75,563,268.5 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 | 151,126,537 | |
| -1 | -151,126,537 |
Now, we try dividing 151,126,537 by 3:
151,126,537 ÷ 3 = 50,375,512.3333
If the quotient is a whole number, then 3 and 50,375,512.3333 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 | 151,126,537 | |
| -1 | -151,126,537 |
Let's try dividing by 4:
151,126,537 ÷ 4 = 37,781,634.25
If the quotient is a whole number, then 4 and 37,781,634.25 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 | 151,126,537 | |
| -1 | 151,126,537 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 257 | 691 | 851 | 5,911 | 9,509 | 15,893 | 25,567 | 177,587 | 218,707 | 588,041 | 4,084,501 | 6,570,719 | 151,126,537 |
| -1 | -23 | -37 | -257 | -691 | -851 | -5,911 | -9,509 | -15,893 | -25,567 | -177,587 | -218,707 | -588,041 | -4,084,501 | -6,570,719 | -151,126,537 |
