Question

Which of the following is the prime factorisation of 24? (a) 6 x 4 (b) 12 x 2 (c ) 2 x 3 x 2 x 2 (d) 2 x 2 x 2 x 2 ​

Answer 1

Step-by-step explanation:

By Prime Factorisation we get :

24 = 2 x 2 x 2 x 3

Since its asked about prime factorisation option A is wrong as 6 is not prime and further it can be deduced to 2 x 3, also 4 can be written as 2 x 2.

The same applies for Option B.

Option D is wrong as it is not the prime factorisation of 24 but 2 x 2 x 2 x 2 = 16

Answer 2

Answer:

The correct option is c) 2 × 3 × 2 × 2

Explanation:

• Option a) is not the correct answer because 6 and 4 is not a prime number..
• Option b) is not the correct answer because 12 is not a prime number....
• Option d) is not the correct answer because 2 × 2×2 ×2 = 16 not 24 but 2 is prime number...
• Hence, option c) is the correct answer 2 × 3 ×2×2 = 24 , 2 and 3 is a prime number...
