correct answer is: d) 2520

Explanation

We know,
From 1 to 9 all natural numbers are 1,2,3,4,5,6,7,8,9.
\therefore To find the required least number first we need to find the LCM of all natural numbers from 1 to 9.
So, The LCM of 1,2,3,4,5,6,7,8,9 is :
2\times2\times3\times5\times7\times2\times3=2520
So that, 2520 is the least number that exactly divisible by all natural numbers from 1 to 9.
Ans: The least number is 2520, that exactly divisible by all natural numbers from 1 to 9.
