77 is written as the product of two prime numbers 7 × 11. Can 702 be written as the product of two prime numbers? If not, why?​

Answer 1

702 can not be written as the product of 2 prime numbers, because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore 702 is a prime number.
