Identifying When to Use LCM or HCF
LCM (Least Common Multiple) and HCF (Highest Common Factor) are both important concepts in mathematics. But how do we know when to use one or the other? Here are some guidelines to help you identify when to use LCM or HCF:
1. When dealing with multiplication or division problems, use LCM.
LCM is used when we need to find the smallest common multiple of two or more numbers. This is often necessary when we want to simplify fractions or add or subtract fractions with different denominators. For example:
- What is the smallest number that is a multiple of both 3 and 4? The LCM of 3 and 4 is 12.
- What is the smallest number that is a multiple of 4, 6, and 8? The LCM of 4, 6, and 8 is 24.
2. When dealing with factors or prime numbers, use HCF.
HCF is used when we need to find the largest common factor of two or more numbers. This is often necessary when we want to simplify fractions or reduce fractions to their lowest terms. For example:
- What is the largest number that divides evenly into both 16 and 24? The HCF of 16 and 24 is 8.
- What is the largest number that divides evenly into 12, 18, and 30? The HCF of 12, 18, and 30 is 6.
3. When dealing with word problems, read carefully to determine if LCM or HCF is needed.
Sometimes word problems will give you clues as to whether LCM or HCF is needed. Look for keywords such as "together," "at the same time," or "simultaneously" which may indicate the need for LCM. Look for keywords such as "divided into," "shared," or "split" which may indicate the need for HCF. For example:
- A factory produces widgets in batches of 4 and 6. What is the smallest number of widgets they can produce at the same time? The answer is the LCM of 4 and 6, which is 12.
- A group of friends want to divide a bag of candy equally among themselves. If there are 15 candies in the bag, what is the largest number of friends they can have? The answer is the HCF of 15 and the number of friends, which is the largest number that can divide evenly into both 15 and the number of friends.
In summary, LCM is used for multiplication and division problems, while HCF is used for factors and prime numbers. When dealing with word problems, read carefully to determine which one is needed. By following these guidelines, you will be able to identify when to use LCM or HCF.

When we have to find a number larger than given number, Then we find LCM.
If we have to find smaller number, than we find HCF.
If we have to find smaller number, than we find HCF.
