Start looking for obvious factors. In this case: any number that ends with 5 or 0 has 5 as a factor. You can also check other small prime numbers to see whether they are factors.
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
95 is the product of two primes, 5 and 19.
