Question

Write all composite numbers between $10$to $18$

Answer 1

Writing all the composite numbers between $10$to $18$ :

Composite numbers : Composite numbers are numbers that have more than two factors. These numbers are called composite numbers.

According to the question,

All the composite numbers between $10$ to $18$ are,

$12=1\times 2\times 2\times 3$(Here $1,2,3,4,6,12$ are the factors, which means that more than two factors)

$14=1\times 7\times 2$ (Here $1,7,2,14$ are the factors, which means that more than two factors)

$15=1\times 3\times 5$ (Here $1,3,5,15$ are the factors, which means that more than two factors)

$16=1\times 2\times 2\times 4$ (Here $1,2,4,8,16$ are the factors, which means that more than two factors)

Therefore, all the composite numbers between $10$ to $18$ are $12,14,15$ and $16$
