Question

What is the smallest 2 digit composite number

Answer 1

Dear student,

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.

The smallest two-digit number is 10.
It can be factorised as 10=2*5. Since it has factors other than 1 and itself, it is a composite number.

​​Therefore the smallest two-digit composite number is 10.
