 Step 2: The common multiples from the multiples of 5 and 14 are 70, 140, . . .
 Step 3: The smallest common multiple of 5 and 14 is 70.
∴ The least common multiple of 5 and 14 = 70.
LCM of 5 and 14 by Division Method
To calculate the LCM of 5 and 14 by the division method, we will divide the numbers(5, 14) by their prime factors (preferably common). The product of these divisors gives the LCM of 5 and 14.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 5 and 14. Write this prime number(2) on the left of the given numbers(5 and 14), separated as per the ladder arrangement.
 Step 2: If any of the given numbers (5, 14) 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 5 and 14 is the product of all prime numbers on the left, i.e. LCM(5, 14) by division method = 2 × 5 × 7 = 70.

LCM of 5 and 14 Examples

Example 1: The GCD and LCM of two numbers are 1 and 70 respectively. If one number is 14, find the other number.
Solution:
Let the other number be b.
∵ GCD × LCM = 14 × b
⇒ b = (GCD × LCM)/14
⇒ b = (1 × 70)/14
⇒ b = 5
Therefore, the other number is 5. 
Example 2: Find the smallest number that is divisible by 5 and 14 exactly.
Solution:
The smallest number that is divisible by 5 and 14 exactly is their LCM.
⇒ Multiples of 5 and 14: Multiples of 5 = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, . . . .
 Multiples of 14 = 14, 28, 42, 56, 70, . . . .
Therefore, the LCM of 5 and 14 is 70.

Example 3: The product of two numbers is 70. If their GCD is 1, what is their LCM?
Solution:
Given: GCD = 1
product of numbers = 70
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 70/1
Therefore, the LCM is 70.
The probable combination for the given case is LCM(5, 14) = 70.
