Methods to Find LCM of 3 and 16

The methods to find the LCM of 3 and 16 are explained below.

By Prime Factorization Method
By Division Method
By Listing Multiples

LCM of 3 and 16 by Prime Factorization

Prime factorization of 3 and 16 is (3) = 3¹ and (2 × 2 × 2 × 2) = 2⁴ respectively. LCM of 3 and 16 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 2⁴ × 3¹ = 48.
Hence, the LCM of 3 and 16 by prime factorization is 48.

LCM of 3 and 16 by Division Method

To calculate the LCM of 3 and 16 by the division method, we will divide the numbers(3, 16) by their prime factors (preferably common). The product of these divisors gives the LCM of 3 and 16.

Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 3 and 16. Write this prime number(2) on the left of the given numbers(3 and 16), separated as per the ladder arrangement.
Step 2: If any of the given numbers (3, 16) is a multiple of 2, divide it by 2 and write the quotient below it. Bring down any number that is not divisible by the prime number.
Step 3: Continue the steps until only 1s are left in the last row.

The LCM of 3 and 16 is the product of all prime numbers on the left, i.e. LCM(3, 16) by division method = 2 × 2 × 2 × 2 × 3 = 48.

LCM of 3 and 16 by Listing Multiples

To calculate the LCM of 3 and 16 by listing out the common multiples, we can follow the given below steps:

Step 1: List a few multiples of 3 (3, 6, 9, 12, 15, 18, 21, . . . ) and 16 (16, 32, 48, 64, 80, 96, 112, . . . . )
Step 2: The common multiples from the multiples of 3 and 16 are 48, 96, . . .
Step 3: The smallest common multiple of 3 and 16 is 48.

∴ The least common multiple of 3 and 16 = 48.

LCM of 3 and 16 Examples

Example 1: The product of two numbers is 48. If their GCD is 1, what is their LCM?

Solution:

Given: GCD = 1
product of numbers = 48
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 48/1
Therefore, the LCM is 48.
The probable combination for the given case is LCM(3, 16) = 48.
Example 2: The GCD and LCM of two numbers are 1 and 48 respectively. If one number is 16, find the other number.

Solution:

Let the other number be a.
∵ GCD × LCM = 16 × a
⇒ a = (GCD × LCM)/16
⇒ a = (1 × 48)/16
⇒ a = 3
Therefore, the other number is 3.
Example 3: Verify the relationship between GCF and LCM of 3 and 16.

Solution:

The relation between GCF and LCM of 3 and 16 is given as,
LCM(3, 16) × GCF(3, 16) = Product of 3, 16
Prime factorization of 3 and 16 is given as, 3 = (3) = 3¹ and 16 = (2 × 2 × 2 × 2) = 2⁴
LCM(3, 16) = 48
GCF(3, 16) = 1
LHS = LCM(3, 16) × GCF(3, 16) = 48 × 1 = 48
RHS = Product of 3, 16 = 3 × 16 = 48
⇒ LHS = RHS = 48
Hence, verified.
