Question

The least number that is divisible by all the numbers from 1 to 8 ( both inclusive) is??​

Answer 1

Answer:

Step-by-step explanation:

The least number divisible by all the numbers from 1 to 10 will be the LCM of these numbers.

We have,

1 = 1

2 = 2 × 1

3 = 3 × 1

4 = 2 × 2

5 = 5 × 1

6 = 2 × 3

7 = 7 × 1

8 = 2 × 2 × 2

9 = 3 × 3

10 = 2 × 5

So, LCM of these numbers = 1 × 2 × 2 × 2 × 3 × 3 × 5 × 7 = 2520

Hence, least number divisible by all the numbers from 1 to 10 is 2520

Answer 2

Answer:

Step-by-step explanation:1 = 1

2 = 2

3 = 3

4= 2*2

5 = 5

6= 2 * 3

7= 7

8 = 2 * 3

LCM = 2 ^3 * 3 * 5 * 7 = 840
