Correct option is B
Given:
The product of two co-prime numbers is 1073.
Concept Used:
The L.C.M (Least Common Multiple) of two co-prime numbers is equal to their product.
Solution:
If two numbers aa and bb are co-prime, then:
L.C.M (a, b) =
Since the numbers are co-prime, the L.C.M of the two numbers will be equal to their product:
L.C.M = 1073
The L.C.M of the two co-prime numbers is 1073.
Thus, the correct option is (b) 1073
Alternate Method:
Given: A B = 1073
Since, HCF(A, B) = 1 (Co- Prime)
Then, LCM HCF = A B
=> LCM = 1073
