Solution

As we know that smallest natural number is $1$ and the two-digit natural number is $10 .$
Multiples of $1 = 1, 2, 3, 4, 5, 6, . . . . . . . . . . . . .$
Multiples of $10 = 10, 20, 30, 40, 50, 60, . . . . . . . . . . . . . . . .$
L.C.M $(1, 10) = 10$
Hence, the least common multiple of the smallest natural and the smallest prime number is $10 .$
