Methods to Find LCM of 14 and 16
Let's look at the different methods for finding the LCM of 14 and 16.
- By Division Method
- By Listing Multiples
- By Prime Factorization Method
LCM of 14 and 16 by Division Method
To calculate the LCM of 14 and 16 by the division method, we will divide the numbers(14, 16) by their prime factors (preferably common). The product of these divisors gives the LCM of 14 and 16.
- Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 14 and 16. Write this prime number(2) on the left of the given numbers(14 and 16), separated as per the ladder arrangement.
- Step 2: If any of the given numbers (14, 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 14 and 16 is the product of all prime numbers on the left, i.e. LCM(14, 16) by division method = 2 × 2 × 2 × 2 × 7 = 112.
LCM of 14 and 16 by Listing Multiples
To calculate the LCM of 14 and 16 by listing out the common multiples, we can follow the given below steps:
- Step 1: List a few multiples of 14 (14, 28, 42, 56, . . . ) and 16 (16, 32, 48, 64, 80, 96, 112, . . . . )
- Step 2: The common multiples from the multiples of 14 and 16 are 112, 224, . . .
- Step 3: The smallest common multiple of 14 and 16 is 112.
∴ The least common multiple of 14 and 16 = 112.
LCM of 14 and 16 by Prime Factorization
