SUMMARY

The discussion centers on calculating the number of distinct products that can be formed using 2 to 4 of the prime numbers 2, 3, 5, and 7, with 6 copies of each available. Since these numbers are prime and share no common factors, the products will be unique combinations of these primes. The total distinct products can be derived from combinations of these numbers, leading to a definitive count based on combinatorial mathematics.

PREREQUISITES
  • Understanding of prime numbers and their properties
  • Basic knowledge of combinatorial mathematics
  • Familiarity with multiplication of integers
  • Ability to calculate combinations
NEXT STEPS
  • Research combinatorial mathematics to understand product combinations
  • Learn about the properties of prime numbers and their implications in multiplication
  • Explore methods for calculating distinct products from sets of numbers
  • Investigate the application of combinatorial principles in number theory
USEFUL FOR

Mathematicians, educators, students studying number theory, and anyone interested in combinatorial problems involving prime numbers.

You have 6 copies of each of the numbers 2,3,5,7. How many different numbers can be obtained as the product of between 2 and 4 of your numbers?

any ideas? - as a first easy step, i would notice the 2,3,5,7 share no factors as they are prime
