Write the smallest 5-digit number and express it in the form of its prime factors by tree diagram.

Solution:

Prime numbers are the numbers that have only two factors, that are, 1 and the number itself.

The smallest 5-digit number is ten thousand represented as 10,000 and its prime factorization is shown below using the tree diagram.

Thus, the smallest 5-digit number is 10000, and its prime factorisation using tree diagram is 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5.

Write the smallest 5-digit number and express it in the form of its prime factors by tree diagram.

Summary:

The smallest 5-digit number is ten thousand represented as 10,000 and its prime factorization is 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5.
