There is no LCM for less than two numbers. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
LCM(3, 17, 51) = 51
The two numbers are prime so their LCM is their product, which is 51.
The LCM is 1377.
The LCM is 255.
The LCM of 34 and 51 is102.
The LCM of 31 and 51 is 1,581.
The LCM of 51 and 80 is 4080
The LCM is 38352.
