What is the lcm AB?
In arithmetic and number theory, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by lcm(a, b), is the smallest positive integer that is divisible by both a and b.
What is the HCF of a B and AB?
For any integers ‘a’ and ‘b’ with HCF (a,b)= 1, what is HCF (a + b, a-b) equal to? Hence it can be concluded that for any integer ‘a’ and ‘b’ with H.C.F(a,b)= 1, the H.C.F. (a + b, a – b)will always be equal to either 1 or 2. Hence option (C)is correct.
What is the lcm of a/b c?
By definition the lcm of the integers a, b and c is the smallest natrual number divisible by all of them, likewise for the lcm of a and b.
What is LCM and GCD?
The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both. The greatest common divisor (GCD) of two integers is the largest positive integer dividing both. The product of the two numbers is the product of the LCM and the GCD.
Why do we use LCM?
In math problems where we pair two objects against each other, the LCM value is useful in optimizing the quantities of the given objects. Also, in computer science, the LCM of numbers helps design encoded messages using cryptography.
What is the smallest multiple of 10?
The smallest multiple of 10 is 1 multiplied by 10, i.e., 10. The other consecutive multiples of 10 can be found by multiplying 10 by 2, 3, 4, and 5, respectively. So, the first five multiples of 10 are: {10,20,30,40,50}. Now we will find the factors of multiples of 20.

How do you find the LCM in C++?
if(a>b) lcm = a; else lcm = b; After this, a while loop runs. In this loop, if LCM is divisible by a as well as b, it is the LCM of the two numbers and is displayed. If not, LCM is incremented until this condition is fulfilled.
Who discovered LCM?
mathematician Euclid
… algorithm, procedure for finding the greatest common divisor (GCD) of two numbers, described by the Greek mathematician Euclid in his Elements (c. 300 bc). The method is computationally efficient and, with minor modifications, is still used by computers.
