Question

What is the least number hat is divisible by from all the numbers from 1 to 10?​

Answer 1

Factors of 1 to 10 numbers

1=1

2=1×2

3=1×3

4=1×2×2

5=1×5

6=1×2×3

7=1×7

8=1×2×2×2

9=1×3×3

10=1×2×5

∴ LCM of number 1 to 10 = LCM (1,2,3,4,5,6,7,8,9,10)

= 1×2×2×2×3×3×5×7 = 2520

Answer 2

Solution

just need the LCM of 1 to 10

therefore.LCM(1,2,3,4,5,6,7,8,9,10)=2520

so the minimum number which divisible by the numbers from 1 to 10 is =2520
