How to Calculate LCM Step by Step with Examples

Basic Calculator – Add, Subtract, Multiply, Divide

What is Basic Calculator?

A Basic Calculator is a simple, convenient online tool that performs fundamental arithmetic operations like addition, subtraction, multiplication, and division. Unlike scientific calculators, it focuses on the most common everyday calculations, making it perfect for students, professionals, and anyone needing a quick answer. With the Basic Calculator, you can enter an arithmetic expression—such as 12+4*3-6/2—and get instant, accurate results.

Formula or Logic Behind Basic Calculator

The Basic Calculator follows the standard order of math operations, also known as BODMAS (Brackets, Order, Division, Multiplication, Addition, Subtraction). It evaluates arithmetic expressions from left to right, solving brackets first, followed by division and multiplication, then finally addition and subtraction. For example, in the expression 3 + 5 × 2, multiplication is performed first (5 × 2 = 10), then added to 3 for a final answer of 13. This logic ensures accuracy and consistency just like a handheld calculator you may use at home or in school.

Common Basic Calculator Operations

Operation	Example
Addition	7 + 4 = 11
Subtraction	10 - 3 = 7
Multiplication	6 * 5 = 30
Division	28 / 7 = 4
Mixed	8 + 2 * 3 = 14
Parentheses	(8 + 2) * 3 = 30

Steps to Use the Basic Calculator

Enter the required number or values as an arithmetic expression (e.g., 14+15/5)
Click on the 'Calculate' button

FAQs on LCM Calculator – Find the Least Common Multiple Online

1. What is the least common multiple (LCM)?

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more numbers. It's useful for solving problems involving fractions and finding common denominators. Understanding LCM is a fundamental concept in arithmetic.

2. How do you calculate the LCM of two numbers?

There are several methods to calculate the LCM. One common method is to list the multiples of each number until you find the smallest multiple they share. Another is using prime factorization: find the prime factors of each number, take the highest power of each prime factor, and multiply them together. Our LCM calculator provides an easy way to calculate the LCM for you.

3. How to find the LCM of three or more numbers?

Finding the LCM of three or more numbers involves the same principle as finding it for two numbers. You can either list the multiples or use prime factorization. The prime factorization method is generally more efficient for larger numbers or more numbers. Our online LCM calculator easily handles multiple numbers.

4. What is the LCM of 12 and 18?

The LCM of 12 and 18 is 36. This can be found by listing the multiples of 12 (12, 24, 36, 48...) and 18 (18, 36, 54...) and identifying the smallest common multiple. Alternatively, using prime factorization: 12 = 2² x 3 and 18 = 2 x 3², resulting in LCM = 2² x 3² = 36.

5. What is the difference between LCM and HCF?

The Least Common Multiple (LCM) is the smallest number that is a multiple of two or more numbers, while the Highest Common Factor (HCF), also known as the Greatest Common Divisor (GCD), is the largest number that divides exactly into two or more numbers. They are inverse concepts; finding one often helps in finding the other.

6. What are some real-life applications of LCM?

LCM has practical applications in various situations. For example, determining when events coincide (like buses arriving at the same stop) or when tasks needing repeated cycles (like machine operations) will occur simultaneously. It's also crucial in simplifying fractions and solving problems related to time and measurement.

7. How can I use the Vedantu LCM calculator?

Our LCM calculator is user-friendly. Simply enter the numbers you want to find the LCM of, separated by commas or spaces, and click the 'Calculate' button. The result will be displayed instantly, along with a step-by-step solution if available.

8. What is the formula for calculating the LCM?

There isn't one single formula, but methods. One common method uses prime factorization: find the prime factors of each number, take the highest power of each prime factor, and multiply them. Another is using the relationship between LCM and HCF: LCM(a, b) = (a x b) / HCF(a, b).

9. What if I enter a large number into the LCM calculator?

Our LCM calculator is designed to handle a wide range of numbers efficiently. Even with large inputs, you should receive a quick and accurate result. If you experience any issues, please check your input for errors or contact our support.
