LCM problems are most easily done by finding the prime factorization of the two numbers:
18 = 2 * 3^2
20 = 2^2 * 5
The LCM is the product of every prime raised to the highest exponent that appears.
LCM (18, 20) = 2^2 * 3^2 * 5 = 180
The LCM is 10980.
18 = 2x3x3 20 = 2x2x5 lcm = 2x2x3x3x5 = 18x10=180
The LCM of 18 14 and 20 is 1,260.
The LCM of 10, 18, and 20 is 180.
LCM(20, 10, 18) = 180.
The Least Common Multiple (LCM) for 20 8 18 is 360.
The LCM is: 720
The lcm is 180
The LCM is: 360
The LCM of 18 and 20 is 180 Using factorisation method: 18 = 2 x 3² 20 = 2² x 5 lcm = 2² x 3² x 5 = 180
The LCM is: 180
Least Common Multiple (LCM) for 18 20 is 180
