What is the LCM of 24 and 32?
First, we factor both numbers to their primes.
The prime factorization of 24 is:
24 = 2 x 2 x 2 x 3
The prime factorization of 32 is:
32 = 2 x 2 x2 x 2 x 2
Next, we identify any shared primes. With 24 and 32, 2 x 2 x 2 is a shared prime number.
Then, we take the shared prime and multiply it with all of the other prime factors.
2 x 2 x 2 x 3 x 2 x 2bl
The red number 2 x 2 x2 is the shared prime factor.
The blue numbers are the other prime factors.
Our answer is 96. The LCM of 32 and 24 is 96.
