A decimal number cannot be written as the product of primes. Instead, It could be rounded, then factorised. 78 = 2*3*13 , 77 = 7*11
7 is a factor of 77 so it cannot be a prime. So it has to be composite.It is composite since 7 x 11 is 77 and those are both primes. That is to say, it is the product of two primes and that makes it composite.
There are no two primes whose product is 50.There are no two primes whose product is 50.There are no two primes whose product is 50.There are no two primes whose product is 50.
The products of the primes are the composites.
1450 as a product of primes = 2 * 5 * 5 * 29
20 as a product of primes = 2 * 2 * 5
