HCF and LCM definitions, formulas and examples are provided here. Visit BYJU’S to learn the full form of LCM in Maths and the full form of HCF in Maths and their methods.
From all the factors, identify the maximum number of times each prime factor appears. The product of the prime factors occurring in maximum numbers is the LCM of the given set of numbers. Let us use the steps in the following example: find the LCM of 8 and 24. ...

Learn Properties of HCF and LCM and the relation between LCM and HCF of natural numbers with examples. Formula to find HCF and LCM of fractions at BYJU'S.
Step 2 : Write the prime factors common to all the three numbers is 1071 ( Here powers of the numbers to be take lowest values from all the common prime factors) Step 3 : So HCF of the numbers 321, 428 and 535 is 107 LCM (Lowest Common Multiple) LCM is the least dividend which ...
Prime factors of 70 = 2 × 5 × 7 LCM: 2 × 3 × 5 × 7 HCF: 5 Verifying the relationship: LCM × HCF = 2 × 3 × 5 × 5 × 7 = 1050 Product of two numbers = 15 × 70 = 1050 From above you can see that LCM (15, 70) × HCF(15, 70) = Product of two numbers ...
Now, the product of all these highest powers of prime factors will be equal to the LCM. Trick 2 - Note the numbers in a horizontal line and separate them with the help of commas. Take the smallest prime number and divide the given number from it. ...
Relation Between LCM and HCFThe HCF of two or more numbers is the highest common factor of the given numbers. It is found by multiplying the common prime factors of the given numbers. Whereas the Least Common Multiple (LCM) of two or more numbers is the smallest number among all common ...
The sum of two non co–prime numbers added to their HCF gives us 91. How many such pairs are possible? 2 4 3 6 Choice C 3 CAT Number System: HCF LCM basics There are 2 numbers such that a > b, HCF (a, b) = h and LCM (a, b) = l. What is the LCM of a – b and ...
The LCM and HCF calculator (also called the LCD and GCD finder) will determine the least common multiple and greatest common factor of a set of two to n numbers. You can also compute the LCM and HCF by hand or use the LCM calculator or the HCF calculator
