• Step 2: The common multiples from the multiples of 14 and 26 are 182, 364, . . .
• Step 3: The smallest common multiple of 14 and 26 is 182.

∴ The least common multiple of 14 and 26 = 182.

LCM of 14 and 26 by Division Method

To calculate the LCM of 14 and 26 by the division method, we will divide the numbers(14, 26) by their prime factors (preferably common). The product of these divisors gives the LCM of 14 and 26.

• Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 14 and 26. Write this prime number(2) on the left of the given numbers(14 and 26), separated as per the ladder arrangement.
• Step 2: If any of the given numbers (14, 26) 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 26 is the product of all prime numbers on the left, i.e. LCM(14, 26) by division method = 2 × 7 × 13 = 182.
