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.
