Question

pls answer the 2nd question

Answer 1

LCM 15 & 6 = 30

smallest 6digit number = 100000

30 x 3334= 100020 + 2 = 100022

Smallest 6digit number = 100022

Answer 2

We know that least number of 6 digits is 100000.

LCM of 15 and 6 = 3 * 5 * 2

                           = 30.

On dividing 100000 by 30, the remainder obtained is 10.

Now,

The least number of 6 digits which is exactly divisible by 30:

⇒ 100000 + (30 - 10)

⇒ 100000 + 20

⇒ 100020.

Therefore, the smallest 6-digit number = 100020.

Hope it helps!
