2. LCM of [tex]22 \cdot 33 \cdot 55[/tex] and [tex]25 \cdot 33 \cdot 52[/tex].

Q2. Identify the greatest common divisor of the following pair of integers:

- [tex]22 \times 33 \times 55[/tex]
- [tex]25 \times 32 \times 52[/tex]

A. 110
B. 165
C. 330
D. 605

Answer :

Discover how to find GCD and LCM using prime factorization method and determine the greatest common divisor of two integers. Hence, the correct option is b) 165.

We can find the GCD (22 · 33 · 55, 25 · 33 · 52) and LCM (22 · 33 · 55, 25 · 33 · 52) using the prime factorization method as follows:

1. Prime factorize each number

2. Identify common prime factors

3. For GCD, multiply the common prime factors, and for LCM, include all prime factors with highest powers

Identify the greatest common divisor of the given pair of integers (22 × 33 × 55 and 25 × 32 × 52):

By finding the GCD using the steps mentioned earlier, we can determine that the correct answer is b) 165. Hence, the correct option is b) 165.
