What is the difference between LCM and HCF?
The H.C.F. defines the greatest factor present in between given two or more numbers, whereas L.C.M. defines the least number which is exactly divisible by two or more numbers. H.C.F. is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor.How do you find the HCF and lcm of 27 27?
How do you find the HCF and lcm of 27 27?For large numbers, the easiest way to find the HCF and LCM is to use Venn diagrams . 27 27. Step 1: We first need the prime factorisation of both numbers, in which we would use factor trees. However we already have the prime factorisation of 27 27.
How to find the HCF of more than 3 numbers?
The above steps can also be used to find the HCF of more than 3 numbers. Example: Find the HCF of 144 and 160 by division method. Since 160>144, so the dividend will be 160 and the divisor will be 144. Hence, we can see here 16 is the highest number which divides 160 and 144. To calculate the LCM of two numbers 60 and 45.What is the HCF and lcm of 25 35 and 45?
What is the HCF and lcm of 25 35 and 45?From the above expression, we can say 5 is the only common factor for all the three numbers. Therefore, 5 is the HCF of 25, 35 and 45. Example: Find the Least Common Multiple of 36 and 44. Solution: Given, two numbers 36 and 44. Let us find out the LCM, by division method.
What does HCF stand for?
Practise finding the highest common factor (HCF), sometimes called the greatest common divisor, and the lowest common multiple (LCM) of two numbers. Menu Sieve Trees Level 1 Level 2 Level 3 Level 4 Level 5 Level 6 Help More…What is the HCF and lcm of two co-prime numbers?
What is the HCF and lcm of two co-prime numbers?If two numbers are co-prime (having no other common factor except 1),then 1 is their hcf and the product of these two numbers is their lcm. The gven co-prime numbers can both be either prime or composite OR one can be prime and the other can be composite.Examples are listed down
