21
It is typical to only find the lowest common multiple or LCM for a maximum of 3 numbers. The LCM of 3, 2, 7 is 42 and the LCM of 3, 2, 5 is 30.
Multiply them together.
You need at least two numbers to find an LCM. If that's 2, 3 and 7, the LCM is 42.
21 is the LCM of 3 and 7
the lcm of 3 and 7 is 21 and the lcm of 7 and 21 is 21, so the lcm of 3, 7 and 21 is the lcm of 21 and 21 which is 21.
The Least Common Multiple (LCM) of 7, 3, and 6 is 42.
The LCM is 105.
The LCM is 63.
The LCM is: 21LCM of 3 & 7 is 21.
lcm(3, 7, 15) = 105. 3 = 3 7 = 7 15 = 3 x 5 lcm = 3 x 5 x 7 = 105
The LCM is 105.
