LCM of 36 and 63 by Division Method

To calculate the LCM of 36 and 63 by the division method, we will divide the numbers(36, 63) by their prime factors (preferably common). The product of these divisors gives the LCM of 36 and 63.

• Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 36 and 63. Write this prime number(2) on the left of the given numbers(36 and 63), separated as per the ladder arrangement.
• Step 2: If any of the given numbers (36, 63) 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 36 and 63 is the product of all prime numbers on the left, i.e. LCM(36, 63) by division method = 2 × 2 × 3 × 3 × 7 = 252.

LCM of 36 and 63 by Prime Factorization
