1.	The least number that is divisible by all the numbers from 1 to 10
Answer» The least number divisible by all the numbers from 1 to 10 will be the LCM of these numbers.We have,1 = 12 = 2 × 13 = 3 × 14 = 2 × 25 = 5 × 16 = 2 × 37 = 7 × 18 = 2 × 2 × 29 = 3 × 310 = 2 × 5So, LCM of these numbers = 1 × 2 × 2 × 2 × 3 × 3 × 5 × 7 = 2520Hence, least number divisible by all the numbers from 1 to 10 is 2520
