3 = 3 x 1
6 = 3 x 2
21 = 3 x 7
51 = 3 x 17
'3' is a common factor throughout.
Hence

The LCM is 60. (3 and 5 are prime numbers) 3 = 3 x 1 = 31 4 = 2 x 2 = 22 5 = 5 x 1 = 51 6 = 2 x 3 = 21 x 31 The LCM is the product of the highest exponents of the primes within the numbers. LCM = 22 x 3 x 5 = 60
No, the LCM is 6.
If that's 21, 15 and 6, the LCM is 210. If that's 2115 and 6, the LCM is 4230.
The LCM is 84.
lcm(3, 4) = 12 lcm(3, 6) = 6 lcm(4, 6) = 12 lcm(3, 4, 6) = 12.
