# Write a program to find hcf and lcm of two numbers

Enter the 1st number: In this program we are using the following logic: We know that LCM of two numbers in simple terms is the least number which is divisible by both the numbers. We also know that the LCM of two numbers can never be greater than the product of the two numbers. A factor of a given number is every number that divides exactly into that number. Write down all factors of The factors of 10 are 1, 2, 5, Number 1 and the number itself are always factors of any number.

## Java Program to Find HCF LCM of Two Numbers

In other words, the prime number can be divided only by 1 and by itself. The prime numbers less than 20 are 2,3,5,7,11,13,17,19 Find all prime factors of All the factors of 30 are 30, 15, 10, 6, 5, 3, 2, 1 But only 5, 3 and 2 are prime numbers. Thefore all prime factors of 30 are 2, 3 and 5.

In fact, all whole numbers that are not prime are composite except for 1 and 0, which are not prime and not composite. The composite numbers less than 20 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18 The simple divisibility rules will help you to find factors of a number. The number is divisible by: Number is divisible by 9 why?

Can you check it? When two or more numbers have the same factor, that factor is called a common factor. Example Find all the common factors of 12 and Factors of 12 are 1, 2, 3, 4, 6, Factors of 18 are 1, 2, 3, 6, The common factors of 12 and 18 are 1, 2, 3 and 6.

The Highest Common Factor H. F of two or more numbers is the largest number that divides evenly into both numbers. In other words the H. F is the largest of all the common factors. The common factors or of 12 and 18 are 1, 2, 3 and 6. The largest common factor is 6, so this is the H. The best way is to keep finding the factors of the smaller number, starting from the largest factor.

The first factor of the smaller number that is also a factor of the larger number is a H. F is useful when simplifying fractions. Find all prime factors of both numbers. Write both numbers as a multiplication of prime numbers. Find the Highest Common Factor H.

Finding all prime factors of We will start with the smallest prime number and we will divide into it if we can the divisibility rules come handy. We will do the same with the result or quotientand we will keep dividing by prime numbers until we have 1 as a quotient. Each time we write the prime factor to the right and the quotient below:Command Line Arguments Questions for TCS.
