LCM of 4 and 16 is 16. The Least Common Multiple, or LCM, is the smallest number that can be evenly split into all of the numbers being addressed, whether they are two or more. The smallest number among all common multiples of 4 and 16 is the LCM of 4 and 16. (4, 8, 12, 16, 20, 24, 28,…) and (16, 32, 48, 64, 80, 96,…) are the first few multiples of 4 and 16 correspondingly. To find the LCM of Two Numbers that is 4 and 16, there are three typical methods: listing multiples, division method, and prime factorization.

LCM of 4 and 16 Solved Example
Question: The product of two numbers is 64. If their GCD is 4, what is their LCM?
Solution: Given: GCD = 4
product of numbers = 64
LCM × GCD = product of numbers
LCM = Product/GCD = 64/4
Therefore, the LCM is 16.
The probable combination for the given case is LCM(4, 16) = 16.
