The gcdlcm() function in Ruby returns an array with the greatest common divisor and the least common multiple of the two integers. GCD signifies the greatest common divisor which divides both the numbers and lcm signifies the least common multiple of both the numbers

Syntax: number1.gcdlcm(number2)

Parameter: The function requires two numbers whose gcd and lcm is returned.

Return Value: The function returns an array which consists of the gcd and lcm of two numbers

Example #1:

# Ruby program of Integer gcdlcm() function

# Initializing the numbers
num1 = 10
num2 = 15
num3 = 21
num4 = 14

# Prints the gcd and lcm
puts num1.gcdlcm(num2)
puts
puts num3.gcdlcm(num4)

Output:

5
30

7
42

Example #2:

# Ruby program of Integer gcdlcm() function

# Initializing the numbers
num1 = 22
num2 = 18
num3 = 30
num4 = 25

# Prints the gcd value
puts num1.gcdlcm(num2)
puts
puts num3.gcdlcm(num4)

Output:

2
198

5
150
