Detailed Solution

Concept- The numbers that divide 150 are known as the factors of 150. When two factors are multiplied together, the result is 150. So, we'll look for pairs of 150 that, when multiplied, produce the result 150.
Question Image and Question Image are definitely the factors of 150 because both divide 150 and Question ImageNow let us divide 150 by 2. We getQuestion Image. So, 2 is the factor of 150. Here, 75 is the quotient. Thus, 75 is also the factor of 150.
Now let us divide 150 by 3. We get Question Image. Because 3 divides 150, so 3 is the factor of 150. Here, 50 is the quotient. Thus, 50 is also the factor of 150.
If we divide the number by 4, we get Question Image. Because 37.5 is not the whole number so 4 is not a factor of 150.
If we divide the number by 5, we get Question Image. Because 5 divides 150, so 5 is a factor of 150. Here, 30 is the quotient. Thus, 30 is also a factor of 150.
If we divide the number by 6, we get Question Image. Thus, 6 and 25 are also the factors of 150.
Dividing by 7, we get Question Image. Thus, 7 is not a factor of 150.
Because the number does not get divided by 4 so it will not get divided by 8 also.
Dividing by 9, we get Question Image so 9 is not a factor of 150.
Dividing by 10, we get Question Image. So, 10 and 15 are factors of 150.
As we can see, there will be no more factors because 150 will not divide Question Image, 12 (not divisible by 4 or 8Question Image and Question Image. So, 15 factors will repeat.
Therefore, the obtained factors are 1,2,3,5,6,10,15,25,30,50,75,150.
Hence, the correct answer is option 2) 1,2,3,5,6,10,15,25,30,50,75,150.
