If the product of two integers is 320 and their least common multiple is 80, what is their greatest common divisor? a) 2 b) 4 c) 5 d) 8 e) cannot be determined
1. (10 points) GCD Algorithm The greatest common divisor of two integers a and b where a 2 b is equal to the greatest common divisor of b and (a mod b). Write a program that implements this algorithm to find the GCD of two integers. Assume that both integers are positive. Follow this algorithm: 1. Call the two integers large and small. 2. If small is equal to 0: stop: large is the GCD. 3. Else, divide large by...
PYTHON In mathematics, the Greatest Common Divisor (GCD) of two integers is the largest positive integer that divides the two numbers without a remainder. For example, the GCD of 8 and 12 is 4. Steps to calculate the GCD of two positive integers a,b using the Binary method is given below: Input: a, b integers If a<=0 or b<=0, then Return 0 Else, d = 0 while a and b are both even do a = a/2 b = b/2...
Let A = {2, 3, . . . , 50}, that is, A is the set of positive integers greater than 1 and less than 51. Determine the smallest number x such that every subset of A having x elements contains at least two integers that have a common divisor greater than 1, and justify your answer. (5 marks) Let A {2,3, ,50}, that is, A is the set of positive integers greater than 1 and less than 51. Determine...
Spring 2020 CSCI 2450: HW5 (Programming Assignment (10 points) Answer any ONE of the following problems. If you answer both of them, you will get bonus points. Use any instructions and Irvine procedures we covered till now. These problems might require instructions from chapter 07. Problem 1: Greatest Common Divisor ( GCD) Greatest Common Divisor (GCD): The greatest common divisor (GCD) of two integers is the largest integer that will evenly divide both integers. The GCD algorithm involves integer division...

The least common multiple (lcm) of two positive integers u and v is the smallest positive integer that is evenly divisible by both u and v. Thus, the lcm of 15 and 10, written lcm (15,10), is 30 because 30 is the smallest integer divisible by both 15 and 10. Write a function lcm() that takes two integer arguments and returns their lcm. The lcm() functon should calculate the least common multiple by calling the gcd() function from program 7.6...

In Java, using only recursion. Ask the user for a list of integers. Display the greatest number in the sequence. Allow any non-integer to end the input. DO NOT USE LOOPS. We are currently learning recursion and can only use recursion. Please provide notes so to better understand. Please describe how inputting a string will end the input section and then go on to execute what number is greater within the entire user input. -------------------------------------------------------------------------------- Standard Input 5 20...
