Question

Write the smallest $5$-digit number and express as a product of prime numbers.

Answer 1

Step 1: Identifying the smallest $5$- digit number

The smallest $5$-digit number $=10000$

Step 2: Prime factorisation of the smallest $5$-digit number

Therefore, the smallest $5$-digit number expressed as product of primes $=2\times 2\times 2\times 2\times 5\times 5\times 5\times 5$
