LCM of 11 and 44 by Listing Multiples

To calculate the LCM of 11 and 44 by listing out the common multiples, we can follow the given below steps:

• Step 1: List a few multiples of 11 (11, 22, 33, 44, 55, 66, . . . ) and 44 (44, 88, 132, 176, 220, 264, 308, . . . . )
• Step 2: The common multiples from the multiples of 11 and 44 are 44, 88, . . .
• Step 3: The smallest common multiple of 11 and 44 is 44.

∴ The least common multiple of 11 and 44 = 44.

LCM of 11 and 44 by Division Method

To calculate the LCM of 11 and 44 by the division method, we will divide the numbers(11, 44) by their prime factors (preferably common). The product of these divisors gives the LCM of 11 and 44.

• Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 11 and 44. Write this prime number(2) on the left of the given numbers(11 and 44), separated as per the ladder arrangement.
• Step 2: If any of the given numbers (11, 44) 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 11 and 44 is the product of all prime numbers on the left, i.e. LCM(11, 44) by division method = 2 × 2 × 11 = 44.
