Question

Write the smallest 6-digit number having four different digits

Answer 1

Answer:

the smallest 6 digit number having four different digits is 100023

Answer 2

The smallest 6 digit number having four different digits is 100023.

• To form the smallest 6 digit number with four different digits, we have to use the first four whole numbers : 0,1,2,3.

• Now,we cannot use the zero as the first digit of the number because it will reduce the count of digits in that number.

• Avoiding zero as the first digit,we can start the number by 1. After that,we have to put 3 zero and lastly we have to put other two digits at the end of the number in ascending order.

• So,the final number will be 100023 and it has four different digits 0,1,2,3.
