3. In mathematics, the greatest common divisor (gcd), sometimes known as the greatest common factor (gcf) or highest common factor (hcf), of two non-zero integers, is the largest positive integer that divides both numbers. The greatest common divisor of a and b is written as gcd (a, b), or sometimes simply as (a, b). For example, gcd (12, 18) = 6, gcd (−4, 14) = 2 and gcd (5, 0) = 5. Two numbers are called co-prime or relatively prime...

Java program: Greatest Common Divisor Write a program which finds the greatest common divisor of two natural numbers a and b Input: a and b are given in a line separated by a single space. Output: Output the greatest common divisor of a and b. Constraints: 1 ≤ a, b ≤ 109 Hint: You can use the following observation: For integers x and y, if x ≥ y, then gcd(x, y) = gcd(y, x%y) Sample Input 1 54 20 Sample Output...

Find the greatest common divisor d = gcd(527, 341). Show all calculation steps. We assume that the modulus is a positive integer. But the definition of the expression a mod n also makes perfect sense if n is negative. Determine the following: a. 7 mod 4 b. 7 mod -4 c. -7 mod 4 d. -7 mod -4

2. Let D be a relation on the natural numbers N deﬁned by D = {(m,n) : m | n} (i.e., D(m,n) is true when n is divisible by m. For this problem, you’ll be proving that D is a partial order. This means that you’ll need to prove that it is reﬂexive, anti-symmetric, and transitive. (a) Prove that D is reﬂexive. (Yes, you already did this problem on one of the minihomework assignments. You don’t have to redo the...
