105 because
if you divide 21 and 15 by three you get 7 and 5 and when you multiply 7, 5, and 3 together you get 105.
The LCM is 3360.
The LCM is 210.
15 and 21 21 and 35
The two numbers that have 105 as their least common multiple (LCM) are 15 and 7. This is because the LCM of two numbers is the smallest number that is a multiple of both numbers. In this case, 15 and 7 are both factors of 105, and no smaller number can be a multiple of both 15 and 7.
The LCM of 15, 21 and 27 is 945.
The LCM is: 105
