Question

Every composite number can be factorised as a product of primes.

• A. True
• B. False

Answer 1

The correct option is A

True

Any integer greater than 1 is either a prime number or can be written as a unique product of prime numbers (ignoring the order).

For example,

210 can be written as $2\times 3\times 5\times 7$ or $3\times 5\times 7\times 2$, or any other possible order in which these primes can be written.

$\therefore$Every composite number can be factorised as a product of primes.
