LCM of 50 and 60 is the smallest number among all common multiples of 50 and 60. The first few multiples of 50 and 60 are (50, 100, 150, 200, . . . ) and (60, 120, 180, 240, 300, 360, . . . ) respectively. There are 3 commonly used methods to find LCM of 50 and 60 - by division method, by listing multiples, and by prime factorization.

Answer: LCM of 50 and 60 is 300.

Explanation:

The LCM of two non-zero integers, x(50) and y(60), is the smallest positive integer m(300) that is divisible by both x(50) and y(60) without any remainder.

The methods to find the LCM of 50 and 60 are explained below.

• By Prime Factorization Method
• By Division Method
• By Listing Multiples

LCM of 50 and 60 by Prime Factorization

Prime factorization of 50 and 60 is (2 × 5 × 5) = 2¹ × 5² and (2 × 2 × 3 × 5) = 2² × 3¹ × 5¹ respectively. LCM of 50 and 60 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 2² × 3¹ × 5² = 300.
Hence, the LCM of 50 and 60 by prime factorization is 300.

LCM of 50 and 60 by Division Method

To calculate the LCM of 50 and 60 by the division method, we will divide the numbers(50, 60) by their prime factors (preferably common). The product of these divisors gives the LCM of 50 and 60.

• Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 50 and 60. Write this prime number(2) on the left of the given numbers(50 and 60), separated as per the ladder arrangement.
• Step 2: If any of the given numbers (50, 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 50 and 60 is the product of all prime numbers on the left, i.e. LCM(50, 60) by division method = 2 × 2 × 3 × 5 × 5 = 300.

LCM of 50 and 60 by Listing Multiples

To calculate the LCM of 50 and 60 by listing out the common multiples, we can follow the given below steps:

• Step 1: List a few multiples of 50 (50, 100, 150, 200, . . . ) and 60 (60, 120, 180, 240, 300, 360, . . . . )
• Step 2: The common multiples from the multiples of 50 and 60 are 300, 600, . . .
• Step 3: The smallest common multiple of 50 and 60 is 300.

∴ The least common multiple of 50 and 60 = 300.

FAQs on LCM of 50 and 60

What is the LCM of 50 and 60?

The LCM of 50 and 60 is 300. To find the least common multiple (LCM) of 50 and 60, we need to find the multiples of 50 and 60 (multiples of 50 = 50, 100, 150, 200 . . . . 300; multiples of 60 = 60, 120, 180, 240 . . . . 300) and choose the smallest multiple that is exactly divisible by 50 and 60, i.e., 300.

If the LCM of 60 and 50 is 300, Find its GCF.

LCM(60, 50) × GCF(60, 50) = 60 × 50
Since the LCM of 60 and 50 = 300
⇒ 300 × GCF(60, 50) = 3000
Therefore, the greatest common factor = 3000/300 = 10.
