The number a and b are co-primes, the LCM of a and b is

(a) 1      ;(b) a     (c) a $+$ b      (d) ab


Given: a and b are co-prime numbers. 


To find: Here we have to find the LCM of a and b.



Solution:


Two numbers are said to be co-prime numbers when they have no other common factor other than one.

  • LCM of two co-prime numbers is their product.
Now, a and b are co-prime numbers. So,
LCM (a, b) = a $\mathbf{\times }$ b = ab
So, LCM of a and b is ab.
