What are the prime factors of 12?

2, 3
1, 2
1, 2, 3
None of the above

hint Hint:

Prime factorization refers to dividing a given number by the smallest possible prime number, also known as factor and finding the group of such prime factors that whn multiplied together, give the original number as the solution.

The correct answer is: 2, 3

Solution-
We know that the smallest prime number that can be used to divide 12 is 2 & 3.
∴ 12 can be factorized as-
12 = 2 * 2 * 3
Hence, Prime factors of 12 are- 2 & 3.
Final Answer- 'Option a' i.e. "2, 3".

Option c is not valid because 1 is not a prime number ( 1 is neither a prime, nor a composite number).

Solve the following equation with the multiplication property of equality.
