Question

What is the least number that divisible by all the natural numbers from 1 to 10 (both inclusive)?

(a) 100
(b) 1260
(c) 2520
(d) 5040

Answer 1

(c) 2520

We have to find the least number that is divisible by all numbers from 1 to 10.
∴ LCM (1 to 10) = $2^3\times 3^2\times 5\times 7=2520$
Thus, 2520 is the least number that is divisible by every element and is equal to the least common multiple.
