Question

How to calculate the LCM (Least Common Multiple) of 4 numbers in Python

Answer 1

a = 12
b = 15
c = 10
d = 75
  
lmc = (a > b and a or b)
lmc = (lmc > c and lmc or c)
lmc = (lmc > d and lmc or d)
 
while 1:
    if (lmc % a) == 0 and (lmc % b) == 0 and (lmc % c) == 0 and (lmc % d) == 0:
        print("The LCM (Least Common Multiple) is:", lmc)
        break
    lmc += 1
  
  

  
  
'''
run:
  
The LCM (Least Common Multiple) is: 300

def getLMC(a, b):
    lmc = (a > b and a or b)

    while 1:
        if (lmc % a) == 0 and (lmc % b) == 0:
            return lmc
        lmc += 1    
        
    
a = 12
b = 15
c = 10
d = 75
  
print("The LCM (Least Common Multiple) is:", getLMC(getLMC(getLMC(a, b), c), d))
