LCM of 24 and 60 by Division Method
To calculate the LCM of 24 and 60 by the division method, we will divide the numbers(24, 60) by their prime factors (preferably common). The product of these divisors gives the LCM of 24 and 60.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 24 and 60. Write this prime number(2) on the left of the given numbers(24 and 60), separated as per the ladder arrangement.
 Step 2: If any of the given numbers (24, 60) 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 24 and 60 is the product of all prime numbers on the left, i.e. LCM(24, 60) by division method = 2 × 2 × 2 × 3 × 5 = 120.

LCM of 24 and 60 Examples

Example 1: The GCD and LCM of two numbers are 12 and 120 respectively. If one number is 24, find the other number.
Solution:
Let the other number be p.
∵ GCD × LCM = 24 × p
⇒ p = (GCD × LCM)/24
⇒ p = (12 × 120)/24
⇒ p = 60
Therefore, the other number is 60. 
Example 2: Verify the relationship between GCF and LCM of 24 and 60.
Solution:
The relation between GCF and LCM of 24 and 60 is given as,
LCM(24, 60) × GCF(24, 60) = Product of 24, 60
Prime factorization of 24 and 60 is given as, 24 = (2 × 2 × 2 × 3) = 2^{3} × 3^{1} and 60 = (2 × 2 × 3 × 5) = 2^{2} × 3^{1} × 5^{1}
LCM(24, 60) = 120
GCF(24, 60) = 12
LHS = LCM(24, 60) × GCF(24, 60) = 120 × 12 = 1440
RHS = Product of 24, 60 = 24 × 60 = 1440
⇒ LHS = RHS = 1440
Hence, verified.
