Question

Least number which is dividable by 12,15,20​

Answer 1

`\huge\boxed{\bf\:1}`

Explanation:

At first, let's factorise the given three numbers.

`12\\= 4 * 3*1\\= \underline {2*2*3*1}`

`15\\= \underline{5*3*1}`

`20\\= 4*5*1\\=\underline {2*2*5*1}`

Here, from the given factors, we can see that the three numbers (12, 15 & 20) don't have any common factors except for 1.

•°• The least numbers divisible by 12, 15 & 20 is 1.

`\rule{150pt}{2pt}`
