a number with only 2 factors (1 and itself ) is called a prime number

Yes. If the numerator and denominator of a fraction are prime, the fraction is in simplest form. The reason is that each number has only two factors, 1 and the number itself. For that reason, it is not possible for the numerator and denominator to have any factors (other than 1) in common.

The LCD is the LCM of all the denominators. The LCM of 13, 34, 532, and 89 is 10,463,908, which is the multiple of the highest power of prime factors from all of the given denominators (22 x 7 x 13 x 17 x 19 x 89 = 10463908). Prime factors of the denominators: 13=13; 34=2 x 17; 532 = 22 x 7 x 19; 89 = 89

There is more than one possible answer. The prime factors of 16 are 2, 2, 2, and 2. It has four prime factors, but only one distinct prime factor. The prime factors of 24 are 2, 2, 2, and 3. It has four prime factors, but only two distinct prime factors. The prime factors of 36 are 2, 2, 3, and 3. It has four prime factors, but only two distinct prime factors.

You cannot. Prime factors are defined in the context of whole numbers, not of fractions.

As a product of its prime factors in exponents: 210*32*52*112 = 27878400
