LCM is a common multiple, the smallest value between the numbers 6 and 14. Did you know? We apply LCM unknowingly in everyday situations like setting alarms and to synchronize traffic lights and when making music.
What is the LCM of 6 and 14?
The LCM of 6 and 14 is 42. We can find the LCM using the Listing multiples method, the prime factorization method and the long division method. These are explained below.
LCM of 6 and 14 Using Listing the Multiples
Step 1: Write down the multiples of the numbers. Don’t stop too early.
Multiples of 6 = 6,12,18,24,30,36,42,…
Multiples of 14= 14,28,42,56,…
Step 2: Find the smallest number common between the written multiples of 6 and 14
The smallest common multiple is 42.
Thus, LCM(6,14) = 42
LCM of 6 and 14 Using Prime Factorization
Step 1: factorize the numbers into its prime factors
6= 2×3
14 = 7×2
Step 2: find the highest powers of the factors of 6 and 14
Step 3: Multiply the highest powers
LCM(6,14) = 42
LCM of 6 and 14 Using Division Method
- Write the numbers 6,14 in a row
- Divide them by their common prime factors, if there is one
- Carry forward the numbers that are left undivided by the previously chosen factor
- Continue dividing until the remainder is ‘1’
- Multiply the divisors to find the LCM
- LCM(6,14) = 42
