that's only which I know choose by yourself

Answer 2

Let us first find the L.C.M of all the numbers between 1 and 10 (both inclusive)

• 1 $=$ 1
• 2 $=$ 2
• 3 $=$ 3
• 4 $=$ 2²
• 5 $=$ 5
• 6 $=$ 2×3
• 7 $=$ 7
• 8 $=$ 2³
• 9 $=$ 3²
• 10 $=$ 2×5
• L.C.M$=$ 2520

Hence 2520 is the least number that is divisible by all the numbers between 1 and 10 (both inclusive)
