What is the lcm of 13 and 27?
To find the least common multiple (LCM) of 13 and 27, we first need to find the prime factorization of each number. The prime factorization of 13 is 13 (as it is a prime number) and the prime factorization of 27 is 3 x 3 x 3. To find the LCM, we take the highest power of each prime factor that appears in either number, so the LCM of 13 and 27 is 13 x 3 x 3 x 3 = 351.

What is the LCM for 27 and 36?
The Least Common Multiple (LCM) of 27 and 36 is the smallest multiple that both numbers share. To find the LCM, you can first determine the prime factorization of each number. The prime factorization of 27 is 3 x 3 x 3 and the prime factorization of 36 is 2 x 2 x 3 x 3. To find the LCM, you take the highest power of each prime factor that appears in either number, which gives you 2 x 2 x 3 x 3 x 3 = 108. Therefore, the LCM of 27 and 36 is 108.
