Find the smallest no of 4 digit which is divisible by 34?

1.Find the smallest no of 4 digit which is divisible by 34?

Answer– Smallest number of 4 digit is 1000.

If we divide 1000 by 34, we will get

 Find the smallest no of 4 digit which is divisible by 34

29 as quotient and 14 as remainder.

So 1000 is not exactly divisible by 34.

If we deduct 14 from 1000

1000-14=986 which is a three digit number but exactly divisible by 34.

If we add 34 to the 986, we will get the next number which will be divisible by 34.

986+34=1020.

Hence 1020 is the smallest number which is exactly divisible by 34.
